OTP_FUSE_PORx register setting during OTP
programming
In the PF0100Z, FUSE_POR1, FUSE_POR2, and
FUSE_POR3 bits are XOR’ed into the
FUSE_POR_XOR bit. The FUSE_POR_XOR bit
has to be 1 for fuses to be loaded during startup.
This can be achieved by setting any one or all of the
FUSE_PORx bits during OTP programming.
In the PF0100AZ, the XOR function is removed. It is
required to set FUSE_POR1, FUSE_POR2, and
FUSE_POR3 bits during OTP programming.

GENERAL PRODUCT CHARACTERISTICS
THERMAL CHARACTERISTICS
4.2 Thermal Characteristics
4.2.1 Power Dissipation
During operation, the temperature of the die should not exceed the operating junction temperature noted in Table 5. To optimize the
thermal management and to avoid overheating, the PF0100Z provides thermal protection. An internal comparator monitors the die
temperature. Interrupts THERM110I, THERM120I, THERM125I, and THERM130I will be generated when the respective thresholds
specified in Table 6 are crossed in either direction. The temperature range can be determined by reading the THERMxxxS bits in register
INTSENSE0.
In the event of excessive power dissipation, thermal protection circuitry will shut down the PF0100Z. This thermal protection will act above
the thermal protection threshold listed in Table 6. To avoid any unwanted power downs resulting from internal noise, the protection is
debounced for 8.0 ms. This protection should be considered as a fail-safe mechanism and therefore the system should be configured such
that this protection is not tripped under normal conditions.

Notes
15. Refer to Figure 4 for Coin Cell mode characteristics over temperature.
16. When VIN is below the UVDET threshold, in the range of 1.8 V VIN < 2.65 V, the quiescent current increases by 50 A, typically.
17. For PFM operation, headroom should be 300 mV or greater.
18. From 0 °C to 85 °C
19. From -40 °C to 85 °C
20. Additional current may be drawn in the coin cell mode when RESETBMCU is pulled up to VSNVS due an internal path from RESETBMCU to VIN.
The additional current is <30A with a pull up resistor of 100k. The i.MX 6x processors have an internal pull up from the POR_B pin to the
VDD_SNVS_IN pin. For i.MX 6x applications, if additional current in the coin cell mode is not desired, use an external switch to disconnect the
RESETBMCU path when VIN is removed. For non-i.MX 6 applications, pull up RESETBMCU to a rail that is off in the coin cell mode.

The PF0100Z PMIC features four buck regulators (up to six independent outputs), one boost regulator, six general purpose LDOs, one
switch/LDO combination and a DDR voltage reference to supply voltages for the application processor and peripheral devices.
The number of independent buck regulator outputs can be configured from four to six, thereby providing flexibility to operate with higher
current capability, or to operate as independent outputs for applications requiring more voltage rails with lower current demands. Further,
SW1 and SW3 regulators can be configured as single/dual phase and/or independent converters. One of the buck regulators, SW4, can
also operate as a tracking regulator when used for memory termination. The buck regulators provide the supply to processor cores and
to other low voltage circuits such as IO and memory. Dynamic voltage scaling is provided to allow controlled supply rail adjustments for
the processor cores and/or other circuitry.
Depending on the system power path configuration, the six general purpose LDO regulators can be directly supplied from the main input
supply or from the switching regulators to power peripherals, such as audio, camera, Bluetooth, Wireless LAN, etc. A specific VREFDDR
voltage reference is included to provide accurate reference voltage for DDR memories operating with or without VTT termination. The
VSNVS block behaves as an LDO, or as a bypass switch to supply the SNVS/SRTC circuitry on the i.MX processors; VSNVS may be
powered from VIN, or from a coin cell.
5.3.2 Control Logic
The PF0100Z PMIC is fully programmable via the I2C interface. Additional communication is provided by direct logic interfacing including
interrupt and reset. Start-up sequence of the device is selected upon the initial OTP configuration explained in the Start-up section, or by
configuring the “Try Before Buy” feature to test different power up sequences before choosing the final OTP configuration.
The PF0100Z PMIC has the interfaces for the power buttons and dedicated signaling interfacing with the processor. It also ensures supply
of critical internal logic and other circuits from the coin cell in case of brief interruptions from the main battery. A charger for the coin cell
is included as well.

GENERAL DESCRIPTION
FUNCTIONAL DESCRIPTION
5.3.2.1 Interface Signals
PWRON
PWRON is an input signal to the IC that generates a turn-on event. It can be configured to detect a level, or an edge using the
PWRON_CFG bit. Refer to section Turn On Events for more details.
STANDBY
STANDBY is an input signal to the IC. When it is asserted the part enters standby mode and when de-asserted, the part exits standby
mode. STANDBY can be configured as active high or active low using the STANDBYINV bit. Refer to the section Standby Mode for more
details.
Note: When operating the PMIC at VIN 2.85 V and VSNVS is programmed for a 3.0 V output, a coin cell must be present to provide
VSNVS, or the PMIC will not reliably enter and exit the STANDBY mode.
RESETBMCU
RESETBMCU is an open-drain, active low output configurable for two modes of operation. In its default mode, it is de-asserted 2.0 to
4.0 ms after the last regulator in the start-up sequence is enabled; refer to Figure 6 as an example. In this mode, the signal can be used
to bring the processor out of reset, or as an indicator that all supplies have been enabled; it is only asserted for a turn-off event.
When configured for its fault mode, RESETBMCU is de-asserted after the start-up sequence is completed only if no faults occurred during
start-up. At anytime, if a fault occurs and persists for 1.8 ms typically, RESETBMCU is asserted, LOW. The PF0100Z is turned off if the
fault persists for more than 100 ms typically. The PWRON signal restarts the part, though if the fault persists, the sequence described
above will be repeated. To enter the fault mode, set bit OTP_PG_EN of register OTP PWRGD EN to “1”. This register, 0xE8, is located
on Extended Page 1 of the register map. To test the fault mode, the bit may be set during TBB prototyping, or the mode may be
permanently chosen by programming OTP fuses.
SDWNB
SDWNB is an open-drain, active low output that notifies the processor of an imminent PMIC shut down. It is asserted low for one 32 kHz
clock cycle before powering down and is then de-asserted in the OFF state.
INTB
INTB is an open-drain, active low output. It is asserted when any fault occurs, provided that the fault interrupt is unmasked. INTB is de-
asserted after the fault interrupt is cleared by software, which requires writing a “1” to the fault interrupt bit.

START-UP
6 Functional Block Requirements and Behaviors
6.1 Start-up
The PF0100Z can be configured to start-up from either the internal OTP configuration, or with a hard-coded configuration built in to the
device. The internal hard-coded configuration is enabled by connecting the VDDOTP pin to VCOREDIG through a 100kohm resistor. The
OTP configuration is enabled by connecting VDDOTP to GND.
For NP devices, selecting the OTP configuration causes the PF0100Z to not start-up. However, the PF0100Z can be controlled through
the I2C port for prototyping and programming. Once programmed, the NP device will startup with the customer programmed configuration.

FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
START-UP
6.1.2 One Time Programmability (OTP)
OTP allows the programming of start-up configurations for a variety of applications. Before permanently programming the IC by
programming fuses, a configuration may be prototyped by using the “Try Before Buy” (TBB) feature. Further, an error correction
code(ECC) algorithm is available to correct a single bit error and to detect multiple bit errors when fuses are programmed.
The parameters that can be configured by OTP are listed below.
• General: I2C slave address, PWRON pin configuration, start-up sequence and timing
• Buck regulators: Output voltage, dual/single phase or independent mode configuration, switching frequency, and soft start ramp
rate
• Boost regulator and LDOs: Output voltage
NOTE: When prototyping or programming fuses, the user must ensure that register settings are consistent with the hardware
configuration. This is most important for the buck regulators, where the quantity, size, and value of the inductors depend on the
configuration (single/dual phase or independent mode) and the switching frequency. Additionally, if an LDO is powered by a buck
regulator, it will be gated by the buck regulator in the start-up sequence.
6.1.2.1 Start-up Sequence and Timing
Each regulator has 5-bits allocated to program its start-up time slot from a turn on event; therefore, each can be placed from position one
to thirty-one in the start-up sequence. The all zeros code indicates that a regulator is not part of the start-up sequence and will remain off.
See Table 11. The delay between each position is equal; however, four delay options are available. See Table 12. The start-up sequence
will terminate at the last programmed regulator.

maximum of 24 ms.

START-UP
6.1.2.2 PWRON Pin Configuration
The PWRON pin can be configured as either a level sensitive input (PWRON_CFG = 0), or as an edge sensitive input (PWRON_CFG =
1). As a level sensitive input, an active high signal turns on the part and an active low signal turns off the part, or puts it into Sleep mode.
As an edge sensitive input, such as when connected to a mechanical switch, a falling edge will turn on the part and if the switch is held
low for greater than or equal to 4.0 seconds, the part will turn off or enter Sleep mode.
6.1.2.3 I2C Address Configuration
The I2C device address can be programmed from 0x08 to 0x0F. This allows flexibility to change the I2C address to avoid bus conflicts.
Address bit, I2C_SLV_ADDR[3] in OTP_I2C_ADDR register is hard coded to “1” while the lower three LSBs of the I2C address
(I2C_SLV_ADDR[2:0]) are programmable as shown in Table 14.
6.1.2.4 Soft Start Ramp Rate
The start-up ramp rate or soft start ramp rate can be chosen from the same options as shown in Dynamic Voltage Scaling.
6.1.3 OTP Prototyping
Before permanently programming fuses, it is possible to test the desired configuration by using the “Try Before Buy” feature. With this
feature, the configuration is loaded from the OTP registers. These registers merely serve as temporary storage for the values to be written
to the fuses, for the values read from the fuses, or for the values read from the default configuration. To avoid confusion, these registers
will be referred to as the TBBOTP registers. The portion of the register map that concerns OTP is shown in Table 136 and Table 137.

FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
16 MHZ AND 32 KHZ CLOCKS
The contents of the TBBOTP registers are initialized to zero when a valid VIN is first applied. The values that are then loaded into the
TBBOTP registers depend on the setting of the VDDOTP pin and on the value of the TBB_POR and FUSE_POR bits. Refer to Table 15.
• If VDDOTP = VCOREDIG (1.5 V), the values are loaded from the default configuration.
• If VDDOTP = 0.0 V, TBB_POR = 0 and FUSE_POR = 1, the values are loaded from the fuses. In the MMPF0100Z, FUSE_POR1,
FUSE_POR2, and FUSE_POR3 are XOR’ed into the FUSE_POR_XOR bit. The FUSE_POR_XOR must be 1 for fuses to be loaded.
This is achieved by setting any one or all of the FUSE_PORx bits. The XOR function is removed in the MMPF0100AZ. It is required
to set all of the FUSE_PORx bits to be able to load the fuses.
• If VDDOTP = 0.0 V, TBB_POR = 0 and FUSE_POR = 0, the TBBOTP registers remain initialized at zero.
The initial value of TBB_POR is always “0”; only when VDDOTP = 0.0 V and TBB_POR is set to “1” are the values from the TBBOTP
registers maintained and not loaded from a different source.
The contents of the TBBOTP registers are modified by I2C. To communicate with I2C, VIN must be valid and VDDIO, to which SDA and
SCL are pulled up, must be powered by a 1.7 to 3.6 V supply. VIN, or the coin cell voltage must be valid to maintain the contents of the
registers. To power on with the contents of the TBBOTP registers, the following conditions must exist; VIN is valid, VDDOTP = 0.0 V,
TBB_POR = 1 and there is a valid turn-on event. Refer to the application note AN4536 for an example of prototyping.
6.1.4 Reading OTP Fuses
As described in the previous section, the contents of the fuses are loaded to the TBBOTP registers when the following conditions are met;
VIN is valid, VDDOTP = 0.0 V, TBB_POR = 0 and FUSE_POR = 1. If ECC were enabled at the time the fuses were programmed, the error
corrected values can be loaded into the TBBOTP registers if desired. Once the fuses are loaded and a turn-on event occurs, the PMIC
will power on with the configuration programmed in the fuses. For more details on reading the OTP fuses, see application note AN4536.
6.1.5 Programming OTP Fuses
The parameters that can be programmed are shown in the TBBOTP registers in the Extended Page 1 of the register map. The PF0100AZ
offers ECC, the control registers for which functions are located in Extended Page 2 of the register map. There are ten banks of twenty-
six fuses each that can be programmed. For more details on programming the OTP fuses, see application note AN4536.
6.2 16 MHz and 32 kHz Clocks
There are two clocks: a trimmed 16 MHz, RC oscillator and an untrimmed 32 kHz, RC oscillator. The 16 MHz oscillator is specified within
-8.0/+8.0%. The 32 kHz untrimmed clock is only used in the following conditions:
• VIN < UVDET
• All regulators are in SLEEP mode
• All regulators are in PFM switching mode
A 32 kHz clock, derived from the 16 MHz trimmed clock, is used when accurate timing is needed under the following conditions:
• During start-up, VIN > UVDET
• PWRON_CFG = 1, for power button debounce timing
In addition, when the 16 MHz is active in the ON mode, the debounce times in Table 26 are referenced to the 32 kHz derived from the
16 MHz clock. The exceptions are the LOWVINI and PWRONI interrupts, which are referenced to the 32 kHz untrimmed clock.

6.2.1 Clock adjustment
The 16 MHz clock and hence the switching frequency of the regulators, can be adjusted to improve the noise integrity of the system. By
changing the factory trim values of the 16 MHz clock, the user may add an offset as small as 3% of the nominal frequency. Contact your
Freescale representative for detailed information on this feature.
6.3 Bias and References Block Description
6.3.1 Internal Core Voltage References
All regulators use the main bandgap as the reference. The main bandgap is bypassed with a capacitor at VCOREREF. The bandgap and
the rest of the core circuitry are supplied from VCORE. The performance of the regulators is directly dependent on the performance of the
bandgap. No external DC loading is allowed on VCORE, VCOREDIG, or VCOREREF. VCOREDIG is kept powered as long as there is a
valid supply and/or valid coin cell. Table 17 shows the main characteristics of the core circuitry.

6.4.1 Modes of Operation
The operation of the PF0100Z can be reduced to five states, or modes: ON, OFF, Sleep, Standby, and Coin Cell. Figure 8 shows the state
diagram of the PF0100Z, along with the conditions to enter and exit from each state.
Figure 8. State Diagram
To complement the state diagram in Figure 8, a description of the states is provided in following sections. Note that VIN must exceed the
rising UVDET threshold to allow a power up. Refer to Table 28 for the UVDET thresholds. Additionally, I2C control is not possible in the
Coin Cell mode and the interrupt signal, INTB, is only active in Sleep, Standby, and ON states.
6.4.1.1 ON Mode
The PF0100Z enters the On mode after a turn-on event. RESETBMCU is de-asserted, high, in this mode of operation.
6.4.1.2 OFF Mode
The PF0100Z enters the Off mode after a turn-off event. A thermal shutdown event also forces the PF0100Z into the Off mode. Only
VCOREDIG and VSNVS are powered in the mode of operation. To exit the Off mode, a valid turn-on event is required. RESETBMCU is
asserted, LOW, in this mode.

6.4.1.3 Standby Mode
• Depending on STANDBY pin configuration, Standby is entered when the STANDBY pin is asserted. This is typically used for low-
power mode of operation.
• When STANDBY is de-asserted, Standby mode is exited.
A product may be designed to go into a Low-power mode after periods of inactivity. The STANDBY pin is provided for board level control
of going in and out of such deep sleep modes (DSM).
When a product is in DSM, it may be able to reduce the overall platform current by lowering the regulator output voltage, changing the
operating mode of the regulators or disabling some regulators. The configuration of the regulators in Standby is pre-programmed through
the I2C interface.
Note that the STANDBY pin is programmable for Active High or Active Low polarity, and that decoding of a Standby event will take into
account the programmed input polarity as shown in Table 22. When the PF0100Z is powered up first, regulator settings for the Standby
mode are mirrored from the regulator settings for the ON mode. To change the STANDBY pin polarity to Active Low, set the STANDBYINV
bit via software first, and then change the regulator settings for Standby mode as required. For simplicity, STANDBY will generally be
referred to as active high throughout this document.
Since STANDBY pin activity is driven asynchronously to the system, a finite time is required for the internal logic to qualify and respond
to the pin level changes. A programmable delay is provided to hold off the system response to a Standby event. This allows the processor
and peripherals some time after a standby instruction has been received to terminate processes to facilitate seamless entering into
Standby mode.
When enabled (STBYDLY = 01, 10, or 11) per Table 23, STBYDLY will delay the Standby initiated response for the entire IC, until the
STBYDLY counter expires. An allowance should be made for three additional 32 k cycles required to synchronize the Standby event.
6.4.1.4 Sleep Mode
• Depending on PWRON pin configuration, Sleep mode is entered when PWRON is de-asserted and SWxOMODE bit is set.
• To exit Sleep mode, assert the PWRON pin.
In the Sleep mode, the regulator will use the set point as programmed by SW1xOFF[5:0] for SW1A/B/C and by SWxOFF[6:0] for SW2,
SW3A/B, and SW4. The activated regulators will maintain settings for this mode and voltage until the next turn-on event. Table 24 shows
the control bits in Sleep mode. During Sleep mode, interrupts are active and the INTB pin will report any unmasked fault event.

6.4.1.5 Coin Cell Mode
In the Coin Cell state, the coin cell is the only valid power source (VIN = 0.0 V) to the PMIC. No turn-on event is accepted in the Coin Cell
state. Transition to the OFF state requires that VIN surpasses UVDET threshold. RESETBMCU is held low in this mode.
If the coin cell is depleted, a complete system reset will occur. At the next application of power and the detection of a Turn-on event, the
system will be re-initialized with all I2C bits including, those that reset on COINPORB are restored to their default states.

6.4.2 State Machine Flow Summary
Table 25 provides a summary matrix of the PF0100Z flow diagram to show the conditions needed to transition from one state to another.
6.4.2.1 Turn On Events
From OFF and Sleep modes, the PMIC is powered on by a turn-on event. The type of Turn-on event depends on the configuration of
PWRON. PWRON may be configured as an active high when PWRON_CFG = 0, or as the input of a mechanical switch when
PWRON_CFG = 1. VIN must be greater than UVDET for the PMIC to turn-on. When PWRON is configured as an active high and PWRON
is high (pulled up to VSNVS) before VIN is valid, a VIN transition from 0.0 V to a voltage greater than UVDET is also a Turn-on event. See
the State diagram, Figure 8, and the Table 25 for more details. Any regulator enabled in the Sleep mode will remain enabled when
transitioning from Sleep to ON, i.e., the regulator will not be turned off and then on again to match the start-up sequence. The following
is a more detailed description of the PWRON configurations:
• If PWRON_CFG = 0, the PWRON signal is high and VIN > UVDET, the PMIC will turn on; the interrupt and sense bits, PWRONI and
PWRONS respectively, will be set.
• If PWRON_CFG = 1, VIN > UVDET and PWRON transitions from high to low, the PMIC will turn on; the interrupt and sense bits,
PWRONI and PWRONS respectively, will be set.
The sense bit will show the real time status of the PWRON pin. In this configuration, the PWRON input can be a mechanical switch
debounced through a programmable debouncer, PWRONDBNC[1:0], to avoid a response to a very short (i.e., unintentional) key press.
The interrupt is generated for both the falling and the rising edge of the PWRON pin. By default, a 30 ms interrupt debounce is applied to
both falling and rising edges. The falling edge debounce timing can be extended with PWRONDBNC[1:0] as defined in the table below.
The interrupt is cleared by software, or when cycling through the OFF mode.

6.4.2.2 Turn Off Events
PWRON Pin
The PWRON pin is used to power off the PF0100Z. The PWRON pin can be configured with OTP to power off the PMIC under the following
two conditions:
1. PWRON_CFG bit = 0, SWxOMODE bit = 0 and PWRON pin is low.
2. PWRON_CFG bit = 1, SWxOMODE bit = 0, PWRONRSTEN = 1 and PWRON is held low for longer than 4.0 seconds.
Alternatively, the system can be configured to restart automatically by setting the RESTARTEN bit.
Thermal Protection
If the die temperature surpasses a given threshold, the thermal protection circuit will power off the PMIC to avoid damage. A turn-on event
will not power on the PMIC while it is in thermal protection. The part will remain in Off mode until the die temperature decreases below a
given threshold. There are no specific interrupts related to this other than the warning interrupt. See Power Dissipation section for more
detailed information.
Undervoltage Detection
When the voltage at VIN drops below the undervoltage falling threshold, UVDET, the state machine will transition to the Coin Cell mode.
6.4.3 Power Tree
The PF0100Z PMIC features six buck regulators, one boost regulator, six general purpose LDOs, one switch/LDO combination, and a
DDR voltage reference to supply voltages for the application processor and peripheral devices. The buck regulators as well as the boost
regulator are supplied directly from the main input supply (VIN). The inputs to all of the buck regulators must be tied to VIN, whether they
are powered on or off. The six general use LDO regulators are directly supplied from the main input supply or from the switching regulators
depending on the application requirements. Since VREFDDR is intended to provide DDR memory reference voltage, it should be supplied
by any rail supplying voltage to DDR memories; the typical application recommends the use of SW3 as the input supply for VREFDDR.
VSNVS is supplied by either the main input supply or the coin cell. Refer to Table 27 for a summary of all power supplies provided by the
PF0100Z.

6.4.4 Buck Regulators
Each buck regulator is capable of operating in PFM, APS, and PWM switching modes.
6.4.4.1 Current Limit
Each buck regulator has a programmable current limit. In an overcurrent condition, the current is limited cycle-by-cycle. If the current limit
condition persists for more than 8.0 ms, a fault interrupt is generated.
6.4.4.2 General Control
To improve system efficiency the buck regulators can operate in different switching modes. Changing between switching modes can occur
by any of the following means: I2C programming, exiting/entering the Standby mode, exiting/entering Sleep mode, and load current
variation. Available switching modes for buck regulators are presented in Table 29.
During soft-start of the buck regulators, the controller transitions through the PFM, APS, and PWM switching modes. 3.0 ms (typical) after
the output voltage reaches regulation, the controller transitions to the selected switching mode. Depending on the particular switching
mode selected, additional ripple may be observed on the output voltage rail as the controller transitions between switching modes. Contact
your Freescale representative for application considerations if you are using load switches in series with the buck regulator outputs.
Table 30 summarizes the Buck regulator programmability for Normal and Standby modes.
Transitioning between Normal and Standby modes can affect a change in switching modes as well as output voltage. The rate of the
output voltage change is controlled by the Dynamic Voltage Scaling (DVS), explained in Dynamic Voltage Scaling. For each regulator, the
output voltage options are the same for Normal and Standby modes.
Table 29. Switching Mode Description
Mode Description
OFF The regulator is switched off and the output voltage is discharged.
PFM In this mode, the regulator is always in PFM mode, which is useful at light loads for optimized efficiency.
PWM In this mode, the regulator is always in PWM mode operation regardless of load conditions.
APS In this mode, the regulator moves automatically between pulse skipping mode and PWM mode depending on load conditions.

When in Standby mode, the regulator outputs the voltage programmed in its standby voltage register and will operate in the mode selected
by the SWxMODE[3:0] bits. Upon exiting Standby mode, the regulator will return to its normal switching mode and its output voltage
programmed in its voltage register.
Any regulators whose SWxOMODE bit is set to “1” will enter Sleep mode if a PWRON turn-off event occurs, and any regulator whose
SWxOMODE bit is set to “0” will be turned off. In Sleep mode, the regulator outputs the voltage programmed in its off (Sleep) voltage
register and operates in the PFM mode. The regulator will exit the Sleep mode when a turn-on event occurs. Any regulator whose
SWxOMODE bit is set to “1” will remain on and change to its normal configuration settings when exiting the Sleep state to the ON state.
Any regulator whose SWxOMODE bit is set to “0” will be powered up with the same delay in the start-up sequence as when powering On
from Off. At this point, the regulator returns to its default ON state output voltage and switch mode settings.
Table 24 shows the control bits in Sleep mode. When Sleep mode is activated by the SWxOMODE bit, the regulator will use the set point
as programmed by SW1xOFF[5:0] for SW1A/B/C and by SWxOFF[6:0] for SW2, SW3A/B, and SW4.
Dynamic Voltage Scaling
To reduce overall power consumption, processor core voltages can be varied depending on the mode or activity level of the processor.
1. Normal operation: The output voltage is selected by I2C bits SW1x[5:0] for SW1A/B/C and SWx[6:0] for SW2, SW3A/B, and SW4.
A voltage transition initiated by I2C is governed by the DVS stepping rates shown in Table 33 and Table 34.
2. Standby Mode: The output voltage can be higher, or lower than in normal operation, but is typically selected to be the lowest state
retention voltage of a given processor; it is selected by I2C bits SW1xSTBY[5:0] for SW1A/B/C and by bits SWxSTBY[6:0] for SW2,
SW3A/B, and SW4. Voltage transitions initiated by a Standby event are governed by the SW1xDVSSPEED[1:0] and
SWxDVSSPEED[1:0] I2C bits shown in Table 33 and Table 34, respectively.
3. Sleep Mode: The output voltage can be higher or lower than in normal operation, but is typically selected to be the lowest state
retention voltage of a given processor; it is selected by I2C bits SW1xOFF[5:0] for SW1A/B/C and by bits SWxOFF[6:0] for SW2,
SW3A/B, and SW4. Voltage transitions initiated by a turn-off event are governed by the SW1xDVSSPEED[1:0] and
SWxDVSSPEED[1:0] I2C bits shown in Table 33 and Table 34, respectively.
Table 31, Table 32, Table 33, and Table 34 summarize the set point control and DVS time stepping applied to all regulators.

The regulators have a strong sourcing capability and sinking capability in PWM mode, therefore the fastest rising and falling slopes are
determined by the regulator in PWM mode. However, if the regulators are programmed in PFM or APS mode during a DVS transition, the
falling slope can be influenced by the load. Additionally, as the current capability in PFM mode is reduced, controlled DVS transitions in
PFM mode could be affected. Critically timed DVS transitions are best assured with PWM mode operation.
The following diagram shows the general behavior for the regulators when initiated with I2C programming, or standby control. During the
DVS period the overcurrent condition on the regulator should be masked.
Figure 10. Voltage Stepping with DVS
Regulator Phase Clock
The SWxPHASE[1:0] bits select the phase of the regulator clock as shown in Table 35. By default, each regulator is initialized at 90 ° out
of phase with respect to each other. For example, SW1x is set to 0 °, SW2 is set to 90 °, SW3A/B is set to 180 °, and SW4 is set to 270 °
by default at power up.
The SWxFREQ[1:0] register is used to set the desired switching frequency for each one of the buck regulators. Table 37 shows the
selectable options for SWxFREQ[1:0]. For each frequency, all phases will be available, this allows regulators operating at different
frequencies to have different relative switching phases. However, not all combinations are practical. For example, 2.0 MHz, 90 ° and
4.0 MHz, 180 ° are the same in terms of phasing. Table 36 shows the optimum phasing when using more than one switching frequency.

Programmable Maximum Current
The maximum current, ISWxMAX, of each buck regulator is programmable. This allows the use of smaller inductors where lower currents
are required. Programmability is accomplished by choosing the number of paralleled power stages in each regulator. The
SWx_PWRSTG[2:0] bits on the Extended Page 2 of the register map control the number of power stages. See Table 38 for the
programmable options. Bit[0] must always be enabled to ensure the stage with the current sensor is chosen. The default setting,
SWx_PWRSTG[2:0] = 111, represents the highest maximum current. The current limit for each option is also scaled by the percentage of
power stages that are enabled.

6.4.4.3 SW1A/B/C
SW1/A/B/C are 2.5 to 4.5 A buck regulators that can be configured in various phasing schemes, depending on the desired cost/
performance trade-offs. The following configurations are available:
• SW1A/B/C single phase with one inductor
• SW1A/B as a single phase with one inductor and SW1C in independent mode with one inductor
• SW1A/B as a dual phase with two inductors and SW1C in independent mode with one inductor
The desired configuration is programmed by OTP by using SW1_CONFIG[1:0] bits in the register map Extended Page 1, as shown in
Table 39.
.
SW1A/B/C Single Phase
In this configuration, all phases A, B, and C, are connected together to a single inductor, thus, providing up to 4.50 A current capability for
high current applications. The feedback and all other controls are accomplished by use of pin SW1CFB and SW1C control registers,
respectively. Figure 11 shows the connection for SW1A/B/C in single phase mode.
During Single Phase mode operation, all three phases will use the same configuration for frequency, phase, and DVS speed set in
SW1CCONF register. However, the same configuration settings for frequency, phase, and DVS speed setting on SW1AB registers should
be used. The SW1FB pin should be left floating in this configuration.

Figure 11. SW1A/B/C Single Phase Block Diagram
SW1A/B Single Phase - SW1C Independent Mode
In this configuration, SW1A/B is connected as a single phase with a single inductor, while SW1C is used as an independent output, using
its own inductor and configurations parameters. This configuration allows reduced component count by using only one inductor for SW1A/
B. As mentioned before, SW1A/B and SW1C operate independently from one another, thus, they can be operated with a different voltage
set point for Normal, Standby, and Sleep modes, as well as switching mode selection and on/off control. Figure 12 shows the physical
connection for SW1A/B in single phase and SW1C as an independent output.

Figure 12. SW1A/B Single Phase, SW1C Independent Mode Block Diagram
Both SW1ALX and SW1BLX nodes operate at the same DVS, frequency, and phase configured by the SW1ABCONF register, while
SW1CLX node operates independently, using the configuration in the SW1CCONF register.
SW1A/B Dual Phase - SW1C Independent Mode
In this mode, SW1A/B is connected in dual phase mode using one inductor per switching node, while SW1C is used as an independent
output using its own inductor and configuration parameters. This mode provides a smaller output voltage ripple on the SW1A/B output.
As mentioned before, SW1A/B and SW1C operate independently from one another, thus, they can be operated with a different voltage
set point for Normal, Standby, and Sleep modes, as well as switching mode selection and on/off control. Figure 13 shows the physical
connection for SW1A/B in dual phase and SW1C as an independent output.

In this mode of operation, SW1ALX and SW1BLX nodes operate automatically at 180 ° phase shift from each other and use the same
frequency and DVS configured by SW1ABCONF register, while SW1CLX node operate independently using the configuration in the
SW1CCONF register.
SW1A/B/C Setup and Control Registers
SW1A/B and SW1C output voltages are programmable from 0.300 to 1.875 V in steps of 25 mV. The output voltage set point is
independently programmed for Normal, Standby, and Sleep mode by setting the SW1x[5:0], SW1xSTBY[5:0], and SW1xOFF[5:0] bits
respectively. Table 40 shows the output voltage coding for SW1A/B or SW1C.
Note: Voltage set points of 0.6 V and below are not supported.

6.4.4.4 SW2
SW2 is a single phase, 2.0 A rated buck regulator. Table 29 describes the modes, and Table 30 show the options for the SWxMODE[3:0]
bits. Figure 15 shows the block diagram and the external component connections for SW2 regulator.
Figure 15. SW2 Block Diagram
SW2 Setup and Control Registers
SW2 output voltage is programmable from 0.400 to 3.300 V; however, bit SW2[6] in register SW2VOLT is read-only during normal
operation. Its value is determined by the default configuration, or may be changed by using the OTP registers. Therefore, once SW2[6] is
set to “0”, the output will be limited to the lower output voltages from 0.400 to 1.975 V with 25 mV increments, as determined by bits
SW2[5:0]. Likewise, once bit SW2[6] is set to “1”, the output voltage will be limited to the higher output voltage range from 0.800 to 3.300 V
with 50 mV increments, as determined by bits SW2[5:0].
In order to optimize the performance of the regulator, it is recommended that only voltages from 2.000 to 3.300 V be used in the high range,
and the lower range be used for voltages from 0.400 to 1.975 V.
The output voltage set point is independently programmed for Normal, Standby, and Sleep mode by setting the SW2[5:0], SW2STBY[5:0]
and SW2OFF[5:0] bits, respectively. However, the initial state of bit SW2[6] will be copied into bits SW2STBY[6], and SW2OFF[6] bits.
Therefore, the output voltage range will remain the same in all three operating modes. Table 54 shows the output voltage coding valid for
SW2.
Note: Voltage set points of 0.6 V and below are not supported.

43. When output is set to > 2.6 V the output will follow the input down when VIN gets near 2.8 V.
44. The higher output voltages available depend on the voltage drop in the conduction path as given by the following equation:
(VINSW2 - VSW2) = ISW2* (DCR of Inductor +RONSW2P + PCB trace resistance).

6.4.4.5 SW3A/B
SW3A/B are 1.25 to 2.5 A rated buck regulators, depending on the configuration. Table 29 describes the available switching modes and
Table 30 show the actual configuration options for the SW3xMODE[3:0] bits.
SW3A/B can be configured in various phasing schemes, depending on the desired cost/performance trade-offs. The following
configurations are available:
• A single phase
• A dual phase
• Independent regulators
The desired configuration is programmed in OTP by using the SW3_CONFIG[1:0] bits.Table 63 shows the options for the SW3CFG[1:0]
bits.
SW3A/B Single Phase
In this configuration, SW3ALX and SW3BLX are connected in single phase with a single inductor a shown in Figure 17. This configuration
reduces cost and component count. Feedback is taken from the SW3AFB pin and the SW3BFB pin must be left open. Although control is
from SW3A, registers of both regulators, SW3A and SW3B, must be identically set.

SW3A/B Dual Phase
SW3A/B can be connected in dual phase configuration using one inductor per switching node, as shown in Figure 18. This mode allows
a smaller output voltage ripple. Feedback is taken from pin SW3AFB and pin SW3BFB must be left open. Although control is from SW3A,
registers of both regulators, SW3A and SW3B, must be identically set. In this configuration, the regulators switch 180 degrees apart.

Figure 19. SW3A/B Independent Output Block Diagram
SW3A/B Setup and Control Registers
SW3A/B output voltage is programmable from 0.400 to 3.300 V; however, bit SW3x[6] in register SW3xVOLT is read-only during normal
operation. Its value is determined by the default configuration, or may be changed by using the OTP registers. Therefore, once SW3x[6]
is set to “0”, the output will be limited to the lower output voltages from 0.40 to 1.975 V with 25 mV increments, as determined by bits
SW3x[5:0]. Likewise, once bit SW3x[6] is set to "1", the output voltage will be limited to the higher output voltage range from 0.800 to
3.300 V with 50 mV increments, as determined by bits SW3x[5:0].
In order to optimize the performance of the regulator, it is recommended that only voltages from 2.00 to 3.300 V be used in the high range
and that that the lower range be used for voltages from 0.400 to 1.975 V.
The output voltage set point is independently programmed for Normal, Standby, and Sleep mode by setting the SW3x[5:0],
SW3xSTBY[5:0], and SW3xOFF[5:0] bits respectively; however, the initial state of the SW3x[6] bit will be copied into the SW3xSTBY[6]
and SW3xOFF[6] bits. Therefore, the output voltage range will remain the same on all three operating modes. Table 64 shows the output
voltage coding valid for SW3x.
Note: Voltage set points of 0.6 V and below are not supported.

Figure 20. SW3AB Single Phase Efficiency Waveforms
6.4.4.6 SW4
SW4 is a 1.0 A rated single phase buck regulator capable of operating in two modes. In its default mode, it operates as a normal buck
regulator with a programmable output between 0.400 and 3.300 V. It is capable of operating in the three available switching modes: PFM,
APS, and PWM, described on Table 29 and configured by the SW4MODE[3:0] bits, as shown in Table 30.
If the system requires DDR memory termination, SW4 can be used in its VTT mode. In the VTT mode, its reference voltage will track the
output voltage of SW3A, scaled by 0.5. Furthermore, when in VTT mode, only the PWM switching mode is allowed. The VTT mode can
be configured by use of VTT bit in the OTP_SW4_CONFIG register.
Figure 21 shows the block diagram and the external component connections for the SW4 regulator.
Figure 21. SW4 Block Diagram
SW4 Setup and Control Registers
To set the SW4 in regulator or VTT mode, bit VTT of the register OTP_SW4_CONF register on Extended Page 1, is programmed during
OTP or TBB configuration; setting bit VTT to “1” will enable SW4 to operate in VTT mode and “0” in Regulator mode. See One Time
Programmability (OTP) for detailed information on OTP configuration.
In Regulator mode, the SW4 output voltage is programmable from 0.400 to 3.300 V; however, bit SW4[6] in the SW4VOLT register is
read-only during normal operation. Its value is determined by the default configuration, or may be changed by using the OTP registers.
Once SW4[6] is set to “0”, the output will be limited to the lower output voltages, from 0.400 to 1.975 V with 25 mV increments, as
determined by the SW4[5:0] bits. Likewise, once the SW4[6] bit is set to "1", the output voltage will be limited to the higher output voltage
range from 0.800 to 3.300 V with 50 mV increments, as determined by the SW4[5:0] bits.

FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
POWER GENERATION
In order to optimize the performance of the regulator, it is recommended that only voltages from 2.000 to 3.300 V be used in the high range
and that that the lower range be used for voltages from 0.400 to 1.975 V.
The output voltage set point is independently programmed for Normal, Standby, and Sleep mode by setting the SW4[5:0], SW4STBY[5:0],
and SW4OFF[5:0] bits, respectively. However, the initial state of the SW4[6] bit will be copied into bits SW4STBY[6], and SW4OFF[6] bits,
so the output voltage range will remain the same on all three operating modes. Table 78 shows the output voltage coding valid for SW4.
Note: Voltage set points of 0.6 V and below are not supported, except in VTT mode.

6.4.5 Boost Regulator
SWBST is a boost regulator with a programmable output from 5.0 to 5.15 V. SWBST can supply the VUSB regulator for the USB PHY in
OTG mode, as well as the VBUS voltage. Note that the parasitic leakage path for a boost regulator will cause the SWBSTOUT and
SWBSTFB voltage to be a Schottky drop below the input voltage whenever SWBST is disabled. The switching NMOS transistor is
integrated on-chip. Figure 23 shows the block diagram and component connection for the boost regulator.

6.4.6 LDO Regulators Description
This section describes the LDO regulators provided by the PF0100Z. All regulators use the main bandgap as reference. Refer to Bias and
References Block Description section for further information on the internal reference voltages.
A Low Power mode is automatically activated by reducing bias currents when the load current is less than I_Lmax/5. However, the lowest
bias currents may be attained by forcing the part into its Low Power mode by setting the VGENxLPWR bit. The use of this bit is only
recommended when the load is expected to be less than I_Lmax/50, otherwise performance may be degraded.
When a regulator is disabled, the output will be discharged by an internal pull-down. The pull-down is also activated when RESETBMCU
is low.

6.4.6.2 Short-circuit Protection
All general purpose LDOs have short-circuit protection capability. The Short-circuit Protection (SCP) system includes debounced fault
condition detection, regulator shutdown, and processor interrupt generation, to contain failures and minimize the chance of product
damage. If a short-circuit condition is detected, the LDO will be disabled by resetting its VGENxEN bit, while at the same time, an interrupt
VGENxFAULTI will be generated to flag the fault to the system processor. The VGENxFAULTI interrupt is maskable through the
VGENxFAULTM mask bit.
The SCP feature is enabled by setting the REGSCPEN bit. If this bit is not set, the regulators will not automatically be disabled upon a
short-circuit detection. However, the current limiter will continue to limit the output current of the regulator. By default, the REGSCPEN is
not set; therefore, at start-up none of the regulators will be disabled if an overloaded condition occurs. A fault interrupt, VGENxFAULTI,
will be generated in an overload condition regardless of the state of the REGSCPEN bit. See Table 90 for SCP behavior configuration.
6.4.6.3 LDO Regulator Control
Each LDO is fully controlled through its respective VGENxCTL register. This register enables the user to set the LDO output voltage
according to Table 91 for VGEN1 and VGEN2; and uses the voltage set point on Table 92 for VGEN3 through VGEN6.

Besides the output voltage configuration, the LDOs can be enabled or disabled at anytime during normal mode operation, as well as
programmed to stay “ON” or be disabled when the PMIC enters Standby mode. Each regulator has associated I2C bits for this. Table 93
presents a summary of all valid combinations of the control bits on VGENxCTL register and the expected behavior of the LDO output.
For more detail information, Table 94 through Table 99 provide a description of all registers necessary to operate all six general purpose
LDO regulators.

6.4.7 VSNVS LDO/Switch
VSNVS powers the low power, SNVS/RTC domain on the processor. It derives its power from either VIN, or coin cell, and cannot be
disabled. When powered by both, VIN takes precedence when above the appropriate comparator threshold. When powered by VIN,
VSNVS is an LDO capable of supplying seven voltages: 3.0, 1.8, 1.5, 1.3, 1.2, 1.1, and 1.0 V. The bits VSNVSVOLT[2:0] in register
VSNVS_CONTROL determine the output voltage. When powered by coin cell, VSNVS is an LDO capable of supplying 1.8, 1.5, 1.3, 1.2,
1.1, or 1.0 V as shown in Table 107. If the 3.0 V option is chosen with the coin cell, VSNVS tracks the coin cell voltage by means of a
switch, whose maximum resistance is 100 . In this case, the VSNVS voltage is simply the coin cell voltage minus the voltage drop across
the switch, which is 40 mV at a rated maximum load current of 400 A.
The default setting of the VSNVSVOLT[2:0] is 110, or 3.0 V, unless programmed otherwise in OTP. However, when the coin cell is applied
for the very first time, VSNVS will output 1.0 V. Only when VIN is applied thereafter will VSNVS transition to its default, or programmed
value if different. Upon subsequent removal of VIN, with the coin cell attached, VSNVS will change configuration from an LDO to a switch
for the “110” setting, and will remain as an LDO for the other settings, continuing to output the same voltages as when VIN is applied,
providing certain conditions are met as described in Table 107.

Notes
66. When the LDO Output voltage is set above 2.6 V the minimum allowed input voltage need to be at least the output voltage plus 0.25 V for proper
regulation due to the dropout voltage generated through the internal LDO transistor.
67. The PSRR of the regulators is measured with the perturbing signal at the input of the regulator. The power management IC is supplied separately
from the input of the regulator and does not contain the perturbed signal. During measurements, care must be taken not to operate in the dropout
region of the regulator under test. VIN3MIN refers to the minimum allowed input voltage for a particular output voltage.

6.4.7.1 Coin Cell Battery Backup
The LICELL pin provides for a connection of a coin cell backup battery or a “super” capacitor. If the voltage at VIN goes below the VIN
threshold (VTL1 and VTL0), contact-bounced, or removed, the coin cell maintained logic will be powered by the voltage applied to LICELL.
The supply for internal logic and the VSNVS rail will switch over to LICELL pin when VIN goes below VTL1 or VTL0, even in the absence
of a voltage at the LICELL pin, resulting in clearing of memory and turning off VSNVS. Applications concerned about this behavior can tie
the LICELL pin to any system voltage between 1.8 V and 3.0 V. A small capacitor should be placed from LICELL to ground under all
circumstances.

Notes
69. During crossover from VIN to LICELL, the VSNVS output voltage may drop to 2.7 V before going to the LICELL voltage. Though this is outside
the specified DC voltage level for the VDD_SNVS_IN pin of the i.MX 6, this momentary drop does not cause any malfunction. The i.MX 6’s RTC
continues to operate through the transition, and as a worst case it may switch to the internal RC oscillator for a few clock cycles before switching
back to the external crystal oscillator.
70. The start-up of VSNVS is not monotonic. It first rises to 1.0 V and then settles to its programmed value within the specified tr1 time.
71. From coin cell insertion to VSNVS = 1.0 V, the delay time is typically 400 ms.

Coin Cell Charger Control
The coin cell charger circuit will function as a current-limited voltage source, resulting in the CC/CV taper characteristic typically used for
rechargeable Lithium-Ion batteries. The coin cell charger is enabled via the COINCHEN bit while the coin cell voltage is programmable
through the VCOIN[2:0] bits on register COINCTL on Table 112. The coin cell charger voltage is programmable. In the ON state, the
charger current is fixed at ICOINHI. In Sleep and Standby modes, the charger current is reduced to a typical 10 A. In the OFF state, coin
cell charging is not available as the main battery could be depleted unnecessarily. The coin cell charging will be stopped when VIN is below
UVDET.

CONTROL INTERFACE I2C BLOCK DESCRIPTION
6.5 Control Interface I2C Block Description
The PF0100Z contains an I2C interface port which allows access by a processor, or any I2C master, to the register set. Via these registers
the resources of the IC can be controlled. The registers also provide status information about how the IC is operating. The SCL and SDA
lines should be routed away from noisy signals and planes to minimize noise pick up. To prevent reflections in the SCL and SDA traces
from creating false pulses, the rise and fall times of the SCL and SDA signals must be greater than 20 ns. This can be accomplished by
reducing the drive strength of the I2C master, via software. The i.MX6 I2C driver defaults to a 40 drive strength. It is recommended to
use a drive strength of 80 or higher to increase the edge times. Alternatively, this can be accomplished by using small capacitors from
SCL and SDA to ground. For example, use 5.1 pF capacitors from SCL and SDA to ground for bus pull-up resistors of 4.8 k.
6.5.1 I2C Device ID
I2C interface protocol requires a device ID for addressing the target IC on a multi-device bus. To allow flexibility in addressing for bus
conflict avoidance, fuse programmability is provided to allow configuration for the lower 3 address LSB(s). Refer to One Time
Programmability (OTP) for more details. This product supports 7-bit addressing only; support is not provided for 10-bit or general call
addressing. Note, when the TBB bits for the I2C slave address are written, the next access to the chip, must then use the new slave
address; these bits take affect right away.
6.5.2 I2C Operation
The I2C mode of the interface is implemented generally following the Fast mode definition which supports up to 400 kbits/s operation
(exceptions to the standard are noted to be 7-bit only addressing and no support for General Call addressing.) Timing diagrams, electrical
specifications, and further details can be found in the I2C specification, which is available for download at:
http://www.nxp.com/acrobat_download/literature/9398/39340011.pdf
I2C read operations are also performed in byte increments separated by an ACK. Read operations also begin with the MSB and each byte
will be sent out unless a STOP command or NACK is received prior to completion.
The following examples show how to write and read data to and from the IC. The host initiates and terminates all communication. The host
sends a master command packet after driving the start condition. The device will respond to the host if the master command packet
contains the corresponding slave address. In the following examples, the device is shown always responding with an ACK to transmissions
from the host. If at any time a NACK is received, the host should terminate the current transaction and retry the transaction.

FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
CONTROL INTERFACE I2C BLOCK DESCRIPTION
6.5.3 Interrupt Handling
The system is informed about important events based on interrupts. Unmasked interrupt events are signaled to the processor by driving
the INTB pin low.
Each interrupt is latched so that even if the interrupt source becomes inactive, the interrupt will remain set until cleared. Each interrupt
can be cleared by writing a “1” to the appropriate bit in the Interrupt Status register; this will also cause the INTB pin to go high. If there
are multiple interrupt bits set the INTB pin will remain low until all are either masked or cleared. If a new interrupt occurs while the processor
clears an existing interrupt bit, the INTB pin will remain low.
Each interrupt can be masked by setting the corresponding mask bit to a 1. As a result, when a masked interrupt bit goes high, the INTB
pin will not go low. A masked interrupt can still be read from the Interrupt Status register. This gives the processor the option of polling for
status from the IC. The IC powers up with all interrupts masked, so the processor must initially poll the device to determine if any interrupts
are active. Alternatively, the processor can unmask the interrupt bits of interest. If a masked interrupt bit was already high, the INTB pin
will go low after unmasking.
The sense registers contain status and input sense bits so the system processor can poll the current state of interrupt sources. They are
read only, and not latched or clearable.
Interrupts generated by external events are debounced; therefore, the event needs to be stable throughout the debounce period before
an interrupt is generated. Nominal debounce periods for each event are documented in the INT summary Table 115 . Due to the
asynchronous nature of the debounce timer, the effective debounce time can vary slightly.
6.5.4 Interrupt Bit Summary
Table 115 summarizes all interrupt, mask, and sense bits associated with INTB control. For more detailed behavioral descriptions, refer

6.5.5 Specific Registers
6.5.5.1 IC and Version Identification
The IC and other version details can be read via identification bits. These are hard-wired on chip and described in Tables 128 to 130.
6.5.5.2 Embedded Memory
There are four register banks of general purpose embedded memory to store critical data. The data written to MEMA[7:0], MEMB[7:0],
MEMC[7:0], and MEMD[7:0] is maintained by the coin cell when the main battery is deeply discharged, removed, or contact-bounced. The
contents of the embedded memory are reset by COINPORB. The banks can be used for any system need for bit retention with coin cell
backup.

CONTROL INTERFACE I2C BLOCK DESCRIPTION
6.5.6 Register Bitmap
The register map is comprised of thirty-two pages, and its address and data fields are each eight bits wide. Only the first two pages can
be accessed. On each page, registers 0 to 0x7F are referred to as 'functional', and registers 0x80 to 0xFF as 'extended'. On each page,
the functional registers are the same, but the extended registers are different. To access registers on Extended Page 1, one must first
write 0x01 to the page register at address 0x7F, and to access registers Extended Page 2, one must first write 0x02 to the page register
at address 0x7F. To access the Functional Page from one of the extended pages, no write to the page register is necessary.
Registers that are missing in the sequence are reserved; reading from them will return a value 0x00, and writing to them will have no effect.
The contents of all registers are given in the tables defined in this chapter; each table is structure as follows:
Name: Name of the bit.
Bit #: The bit location in the register (7-0)
R/W: Read / Write access and control
• R is read-only access
• R/W is read and write access
• RW1C is read and write access with write 1 to clear
Reset: Reset signals are color coded based on the following legend.
Default: The value after reset, as noted in the Default column of the memory map.
• Fixed defaults are explicitly declared as 0 or 1.
• “X” corresponds to Read / Write bits that are initialized at start-up, based on the OTP fuse settings or default if VDDOTP = 1.5 V.
Bits are subsequently I2C modifiable, when their reset has been released. “X” may also refer to bits that may have other
dependencies. For example, some bits may depend on the version of the IC, or a value from an analog block, for instance the sense
bits for the interrupts.

Notes
75. In the PF0100Z FUSE_POR1, FUSE_POR2, and FUSE_POR3 are XOR’ed into the FUSE_POR_XOR bit. The FUSE_POR_XOR has to be 1 for
fuses to be loaded. This can be achieved by setting any one or all of the FUSE_PORx bits. In the PF0100AZ, the XOR function is removed. It is
required to set all of the FUSE_PORx bits to be able to load the fuses.

TYPICAL APPLICATIONS
PF0100Z LAYOUT GUIDELINES
7.2 PF0100Z Layout Guidelines
7.2.1 General Board Recommendations
1. It is recommended to use an eight layer board stack-up arranged as follows:
• High current signal
•GND
• Signal
• Power
• Power
• Signal
•GND
• High current signal
2. Allocate TOP and BOTTOM PCB Layers for POWER ROUTING (high current signals), copper-pour the unused area.
3. Use internal layers sandwiched between two GND planes for the SIGNAL routing.
7.2.2 Component Placement
It is desirable to keep all component related to the power stage as close to the PMIC as possible, specially decoupling input and output
capacitors.
7.2.3 General Routing Requirements
1. Some recommended things to keep in mind for manufacturability:
• Via in pads require a 4.5 mil minimum annular ring. Pad must be 9.0 mils larger than the hole
• Maximum copper thickness for lines less than 5.0 mils wide is 0.6 oz copper
• Minimum allowed spacing between line and hole pad is 3.5 mils
• Minimum allowed spacing between line and line is 3.0 mils
2. Care must be taken with SWxFB pins traces. These signals are susceptible to noise and must be routed far away from power,
clock, or high power signals, like the ones on the SWxIN, SWx, SWxLX, SWBSTIN, SWBST, and SWBSTLX pins. They could be
also shielded.
3. Shield feedback traces of the regulators and keep them as short as possible (trace them on the bottom so the ground and power
planes shield these traces).
4. Avoid coupling traces between important signal/low noise supplies (like REFCORE, VCORE, VCOREDIG) from any switching node
(i.e. SW1ALX, SW1BLX, SW1CLX, SW2LX, SW3ALX, SW3BLX, SW4LX, and SWBSTLX).
5. Make sure that all components related to a specific block are referenced to the corresponding ground.

7.2.4 Parallel Routing Requirements
1. I2C signal routing
• CLK is the fastest signal of the system, so it must be given special care.
• To avoid contamination of these delicate signals by nearby high power or high frequency signals, it is a good practice to
shield them with ground planes placed on adjacent layers. Make sure the ground plane is uniform throughout the whole signal
trace length.
Figure 30. Recommended Shielding for Critical Signals.
• These signals can be placed on an outer layer of the board to reduce their capacitance with respect to the ground plane.
• Care must be taken with these signals not to contaminate analog signals, as they are high frequency signals. Another good
practice is to trace them perpendicularly on different layers, so there is a minimum area of proximity between signals.

TYPICAL APPLICATIONS
PF0100Z LAYOUT GUIDELINES
7.2.5 Switching Regulator Layout Recommendations
1. Per design, the switching regulators in PF0100Z are designed to operate with only one input bulk capacitor. However, it is
recommended to add a high frequency filter input capacitor (CIN_hf), to filter out any noise at the regulator input. This capacitor
should be in the range of 100 nF and should be placed right next to or under the IC, closest to the IC pins.
2. Make high-current ripple traces low-inductance (short, high W/L ratio).
3. Make high-current traces wide or copper islands.
4. Make high-current traces symetrical for dual–phase regulators (SW1, SW3).

THERMAL INFORMATION
7.3 Thermal Information
7.3.1 Rating Data
The thermal rating data of the packages has been simulated with the results listed in Table 5.
Junction to Ambient Thermal Resistance Nomenclature: the JEDEC specification reserves the symbol RθJA or θJA (Theta-JA) strictly for
junction-to-ambient thermal resistance on a 1s test board in natural convection environment. RθJMA or θJMA (Theta-JMA) will be used for
both junction-to-ambient on a 2s2p test board in natural convection and for junction-to-ambient with forced convection on both 1s and
2s2p test boards. It is anticipated that the generic name, Theta-JA, will continue to be commonly used.
The JEDEC standards can be consulted at http://www.jedec.org.
7.3.2 Estimation of Junction Temperature
An estimation of the chip junction temperature TJ can be obtained from the equation:
TJ = TA + (RθJA x PD)
with:
TA = Ambient temperature for the package in °C
RJA = Junction to ambient thermal resistance in °C/W
PD = Power dissipation in the package in W
The junction to ambient thermal resistance is an industry standard value that provides a quick and easy estimation of thermal performance.
Unfortunately, there are two values in common usage: the value determined on a single layer board RθJA and the value obtained on a four
layer board RθJMA. Actual application PCBs show a performance close to the simulated four layer board value although this may be
somewhat degraded in case of significant power dissipated by other components placed close to the device.
At a known board temperature, the junction temperature TJ is estimated using the following equation
TJ = TB + (RθJB x PD) with
TB = Board temperature at the package perimeter in °C
RθJB = Junction to board thermal resistance in °C/W
PD = Power dissipation in the package in W
When the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made.
See Functional Block Requirements and Behaviors for more details on thermal management.
