General Description
The AAT4620 SmartSwitch is a current limited P-channel
MOSFET power switch designed for high-side load-
switching applications in PCMCIA GSM/GPRS/3G modem
cards. Used in conjunction with a super capacitor, the
AAT4620 will ensure that the power ratings of the PCMCIA
host are not exceeded at any time. Featuring two inde-
pendent, programmable current limits and a power loop,
the AAT4620 can ensure that the super capacitor can be
charged without exceeding PCMCIA specifications. The
current limit is set by two external resistors allowing a
±10% current limit accuracy over the normal operating
temperature range. The switch can be controlled from
either of the two enable inputs and in the off condition
will block currents in both directions. The AAT4620 also
incorporates a System READY function which can advise
the system that the super capacitor is fully charged and
ready for use. Adjustable hysteresis is provided with the
addition of an external resistor. The quiescent supply cur-
rent is typically a low 40μA. In shutdown mode, the sup-
ply current decreases to less than 1μA.
The AAT4620 is available in a thermally enhanced,
Pb-free, 12-pin TSOPJW package and is specified over
the -40°C to 85°C temperature range.

Functional Description
The AAT4620 is an integrated P-channel MOSFET load
switch with an upper and lower adjustable current limits
which can be enabled independently, over-temperature
protection, a power loop and a super capacitor charger.
The current limit control is combined with an over tem-
perature thermal limit and power loop circuit to provide
a comprehensive system to protect the load switch and
its supply from load conditions which exceed the supply
specifications. The AAT4620 has been designed specifi-
cally to provide the interface between a PCMCIA host
and PCMCIA card where a super capacitor has been used
to “average out” high pulse currents which would other-
wise exceed the PCMCIA/ Express Card power specifica-
tions. e.g. GSM/ GPRS modem cards, where pulse cur-
rents during transmit signals can exceed the 1A maxi-
mum specification (1.3A in the case of Express Card).
The current limit and over temperature circuits act inde-
pendently. The device current limit is activated when the
output load current exceeds an internal threshold level.
There are two internal current limits which are enabled
independently. The current limit threshold in each case
is determined by external resistors connected between
the two SET pins and ground. The minimum current limit

threshold is specified by ILIM(MIN). If the load condition
maintains the device in current limit and the chip tem-
perature reaches a critical point, then an internal power
loop will reduce the current to a safe level. Connecting
ISETU to ground disables the current limit protection
allowing a low impedance path to the host VCC.
The load switch is turned off by applying a logic high
level to both of the EN pins. When both EN IL and EN IU
are selected ISETU will be selected. The EN function has
logic level thresholds that allow the AAT4620 to be TTL
compatible and may also be controlled by 2.5V to 5.0V
CMOS circuits. The voltage level applied to the EN pins
should not exceed the input supply level present on the
VCC pin. The AAT4620 typically consumes 40μA when
operating, when off, the device draws less then 1μA. In
the off state, current is prevented from flowing between
the input and output.
Under-voltage lockout circuitry ensures that the VCC sup-
ply is high enough for correct operation of the IC. Also
included is a System Ready function which will be acti-
vated when the capacitor voltage is charged and the load
is permitted to take current. For automatic functionality,
this pin can be directly connected to the EN IU pin. An
external resistor is provided to add hysteresis to this
function.
Application Information
ISETU and ISETL Current Limit Set
The AAT4620 current limit is set at two different levels.
Resistors from ISETL and ISETU set the lower and upper
current limit levels respectively.
The ISETL and ISETU nodes operate within a window of
0.75V to 1.5V for resistor values ranging from 93.75 to
1.5M. Resistor values outside this range are not recom-
mended. The ISETL and ISETU source current varies with
the resistor value used according to Table 1. To determine
the resulting current limit multiply the RSETU or RSETL node
voltage times the gain in Table 1. Note that the voltage at
the node varies from 0.75V to 1.5V and the current limit
gain varies depending on the resistor value used.
VISET = RSET · IISET = 0.75V to 1.5V
If the set pin is open circuit or allowed to exceed 2V, all
power devices are disabled and the input is disconnected
from the output. Shorting the set pin to GND enables all
power devices and shorts the VCC to the output pin with
no current limit.
To activate the upper current level (RSETU) pull EN IU low.
To activate the lower current level (RSETL) pull EN IL low.
If both EN IU and EN IL are pulled low the EN IU current
limit level (RSETU) will be selected.

System Ready Hysteresis
(RHYS) and System Ready (RDY)
In internal comparator senses the output voltage and
delivers a ready signal to the external micro controller
when the output voltage reaches 98% of the final value
(VCC). The comparator hysteresis is programmed by a
resistor from the RHYS pin to ground. The RHYS voltage
determines the hysteresis voltage and is equal to the
RHYS source current (1μA) times the RHYS resistance.
VHYST = RHYS · 1μA
= 200kΩ · 1μ
A
= 0.2V
The system ready pin (RDY) is an open drain output that
switches low when the output voltage reaches 98% of
the input voltage. It requires an external pull up resistor
tied to the input voltage with a typical value of 100k.
Power Loop
The AAT4620 power loop limits the load current in the
event that the device power dissipation becomes exces-
sive. The AAT4620 power loop regulates the die tempera-
ture to 100°C, decreasing the load current in increments
of 1/32 of the current limit set point when the die tem-
perature reaches 100°C. When the die temperature
exceeds 100°C it decreases the load current by 1/32 of
the current limit set point. If die temperature is less than
100°C, it increases the load current in increments of 1/32
of the current limit set point until the set current limit
point is reached or the die temperature exceeds 100°C.
The delay time between die temperature measurements
varies depending on the load current limit set point. The
delay ranges from 1ms for a 75mA current limit set point
to 8ms for a 1.5A current limit set point.
For the condition where there is no current limit set point
(shorting RSETU or RSETL to ground) the soft start incre-
ments the current limit is 1/32 steps of 1.2A until the
current reaches 1.2A, at which point the power MOSFET
turns on fully. At this point, the current is limited by the
RDS(ON) of the power MOSFET and other series resistance.
The Power Loop and Over-Temperature Loop then takes
control to limit the current until the output voltage has
fully charged.
Over-Temperature Protection
If the die temperature rate of rise is fast enough to
exceed the power loop regulated temperature, over-
temperature shutdown disables the device. The over-
temperature threshold is 145°C. After over-temperature
shutdown, soft start is initiated once the die temperature
drops to 130°C.
Short Circuit Protection
The series pass power MOSFET turns off completely after
the output has charged to within 18mV of the input volt-
age. This protects the device in the event of a short
circuit applied to the output. Applying a short circuit or
heavy load to the output initiates the digital soft start
where the current ramps from zero to the final pro-
grammed value. The power loop will be activated once
the digital soft start begins.
Under-Voltage Shutdown
Under-voltage lockout enables the device at 2.7V typical
with 100mV of hysteresis. The maximum UVLO level is
3.0V.

Digitally Programmed
Soft Start Current Limit
At turn on, the digital soft start increases the load cur-
rent in discrete levels equal to 1/32 of the final pro-
grammed current limit set point from zero to the final
programmed current limit level.
Reverse Current Blocking
An internal comparator disables the internal pass tran-
sistor when the input voltage is less than the output
voltage blocking any reverse current from the output to
the input.
