General Description
The MAX6305–MAX6313 CMOS microprocessor (µP)
supervisory circuits are designed to monitor more than
one power supply. Ideal for monitoring both 5V and
3.3V in personal computer systems, these devices
assert a system reset if any of the monitored supplies
falls outside the programmed threshold. Low supply
current (15µA) and a small package suit them for
portable applications. The MAX6305–MAX6313 are
specifically designed to ignore fast transients on
any monitored supply.
These devices are available in a SOT23-5 package,
have factory-programmed reset thresholds from 2.5V to
5.0V (in 100mV increments), and feature four power-on
reset timeout periods. Ten standard versions are avail-
able. Contact the factory for availability of non standard
versions.

_______________Detailed Description
The MAX6305–MAX6313 CMOS microprocessor (µP)
supervisory circuits are designed to monitor more than
one power supply and issue a system reset when any
monitored supply falls out of regulation. The MAX6305/
MAX6308/MAX6311 have two adjustable undervoltage
reset inputs (RST IN1 and RST IN2). The MAX6306/
MAX6307/MAX6309/MAX6310/MAX6312/MAX6313 mon-
itor VCC through an internal, factory-trimmed voltage
divider. The MAX6306/MAX6309/MAX6312 have, in
addition, an adjustable undervoltage reset input and a
manual-reset input. The internal voltage divider sets the
reset threshold as specified in the device part number
(Table 1). The MAX6307/MAX6310/ MAX6313 feature an
adjustable undervoltage reset input (RST IN) and an
adjustable overvoltage reset input (OVRST IN) in addition
to the factory-trimmed reset threshold on the VCC moni-
tor. Program the adjustable reset inputs with an external
resistor divider (see Adjustable Reset Inputs section).
Reset Outputs
A µP’s reset input starts the µP in a known state. These
µP supervisory circuits assert reset to prevent code-
execution errors during power-up, power-down, or
brownout conditions.
RESET (MAX6305–MAX6310) and RESET (MAX6311/
MAX6312/MAX6313) are guaranteed to be asserted at
a valid logic level for VCC > 1V (see Electrical
Characteristics). Once all monitored voltages exceed
their programmed reset thresholds, an internal timer
keeps reset asserted for the reset timeout period (tRP);
after this interval, reset deasserts.
If a brownout condition occurs (any or all monitored volt-
ages dip outside their programmed reset threshold),
reset asserts (RESET goes high; RESET goes low). Any
time any of the monitored voltages dip below their reset
threshold, the internal timer resets to zero and reset
asserts. The internal timer starts when all of the moni-
tored voltages return above their reset thresholds, and
reset remains asserted for a reset timeout period. The
MAX6305/MAX6306/MAX6307 feature an active-low,

open-drain, N-channel output. The MAX6308/MAX6309/
MAX6310 feature an active-low, complementary output
structure that both sinks and sources current, and the
MAX6311/MAX6312/MAX6313 have an active-high com-
plementary reset output.
The MAX6305/MAX6308/MAX6311 switch from under-
voltage lockout operation to normal operation between
1.5V < VCC < 2.5V. Below 1.5V, VCC undervoltage-
lockout mode asserts RESET. Above 2.5V, VCC normal-
operation mode asserts reset if RST IN_ falls below the
RST IN_ threshold.
Manual-Reset Input
(MAX6306/MAX6309/MAX6312)
Many µP-based products require manual-reset capability,
allowing an operator or external logic circuitry to initiate a
reset. A logic low on MR asserts reset. Reset remains
asserted while MR is low, and for a reset active timeout
period (tRP) after MR returns high. This input has an inter-
nal 63.5kΩpull-up resistor, so it can be left open if it is not
used. MR can be driven with TTL-logic levels in 5V sys-
tems, with CMOS-logic levels in 3V systems, or with open-
drain/collector output devices. Connect a normally open
momentary switch from MR to GND to create a manual-
reset function; external debounce circuitry is not required.
If MR is driven from long cables or if the device is used in
a noisy environment, connecting a 0.1µF capacitor from
MR to ground provides additional noise immunity.
The MR pin has internal ESD-protection circuitry that may
be forward biased under certain conditions, drawing
excessive current. For example, assume the circuitry driv-
ing MR uses a +5V supply other than VCC. If VCC drops or
browns out lower than +4.7V, MR’s absolute maximum rat-
ing is violated (-0.3V to (VCC + 0.3V)), and undesirable
current flows through the ESD structure from MR to VCC.
To avoid this, it is recommended that the supply for the MR
pin be the same as the supply monitored by VCC. In this
way, the voltage at MR will not exceed VCC.
Adjustable Reset Inputs
The MAX6305–MAX6313 each have one or more reset
inputs (RST IN_ /OVRST IN). These inputs are com-
pared to the internal reference voltage (Figure 1).
Connect a resistor voltage divider to RST IN_ such that
VRST IN_ falls below VRSTH (1.23V) when the monitored
voltage (VIN) falls below the desired reset threshold
(VTH) (Figure 2). Calculate the desired reset voltage
with the following formula:

The ±25nA max input leakage current allows resistors on
the order of megohms. Choose the pull-up resistor in the
divider to minimize the error due to the input leakage cur-
rent. The error term in the calculated threshold is simply:
±25nA x R1
If you choose R1 to be 1MΩ, the resulting error is
±25 x 10-9 x 1 x 106= ±25mV.
Like the VCC voltage monitors on the MAX6306/MAX6307/
MAX6309/MAX6310/MAX6312/MAX6313, the RST IN_
inputs (when used with a voltage divider) are designed to
ignore fast voltage transients. Increase the noise immunity
by connecting a capacitor on the order of 0.1µF between
RST IN and GND (Figure 2). This creates a single-pole
lowpass filter with a corner frequency given by:
f = (1/2π) / (R1 + R2)(R1 x R2 x C)
For example, if R1 = 1MΩand R2 = 1.6MΩ, adding a
0.1µF capacitor from RST IN_ to ground results in a
lowpass corner frequency of f = 2.59Hz. Note that
adding capacitance to RST IN slows the circuit’s overall
response time.
__________Applications Information
Interfacing to µPs with
Bidirectional Reset Pins
Since the RESET output on the MAX6305/MAX6306/
MAX6307 is open drain, these devices interface easily
with µPs that have bidirectional reset pins, such as the
Motorola 68HC11. Connecting the µP supervisor’s
RESET output directly to the microcontroller’s RESET
pin with a single pull-up resistor allows either device to
assert reset (Figure 3).
Negative-Going VCC Transients
In addition to issuing a reset to the µP during power-up,
power-down, and brownout conditions, these devices
are relatively immune to short-duration, negative-going
VCC transients (glitches).
The Typical Operating Characteristics show the
Maximum Transient Duration vs. VCC Reset Threshold
Overdrive, for which reset pulses are not generated.
The graph was produced using negative-going pulses,
starting at VTH max, and ending below the pro-
grammed reset threshold by the magnitude indicated
(reset threshold overdrive). The graph shows the maxi-
mum pulse width that a negative-going VCC transient
may typically have without causing a reset pulse to be
issued. As the amplitude of the transient increases (i.e.,
goes farther below the reset threshold), the maximum
allowable pulse width decreases.
RST IN_/OVRST IN are also immune to negative/positive-
going transients (see Typical Operating Characteristics).
A 0.1µF bypass capacitor mounted close to the RST IN_,
OVRST IN, and/or the VCC pin provides additional tran-
sient immunity.
Ensuring a Valid
RESET
/RESET
Output Down to VCC = 0V
When VCC falls below 1V, push/pull structured RESET/
RESET current sinking (or sourcing) capabilities
decrease drastically. High-impedance CMOS-logic
inputs connected to RESET can drift to undetermined
voltages. This presents no problem in most applica-
tions, since most µPs and other circuitry do not operate
with VCC below 1V. In those applications where RESET
must be valid down to 0V, adding a pull-down resistor
between RESET and ground sinks any stray leakage

currents, holding RESET low (Figure 4). The pull-down
resistor’s value is not critical; 100kΩis large enough not
to load RESET and small enough to pull RESET to
ground. For applications where RESET must be valid to
VCC, a 100kΩpull-up resistor between RESET and VCC
will hold RESET high when VCC falls below 1V (Figure 5).
Since the MAX6305/MAX6306/MAX6307 have open-
drain, active-low outputs, they typically use a pull-up
resistor. With these devices and under these conditions
(VCC < 1V), RESET will most likely not maintain an
active condition, but will drift toward a nonactive level
due to the pull-up resistor and the RESET output’s
reduction in sinking capability. These devices are not
recommended for applications that require a valid
RESET output below 1V.

†The MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/
MAX6313 are available with factory-set VCC reset thresholds from
2.5V to 5V, in 0.1V increments. Insert the desired nominal reset
threshold (from Table 1) into the blanks following the letters UK.
All parts also offer factory-programmed reset timeout periods.
Insert the number corresponding to the desired nominal timeout
period index following the “D” in the part number (D1 = 1ms min,
D2 = 20ms min, D3 = 140ms min, and D4 = 1120ms min). There
are 10 standard versions with a required order increment of 2,500
pieces. Sample stock is generally held on the standard versions
only (see Standard Versions table). Required order increment is
10,000 pieces for non-standard versions. Contact factory for avail-
ability of non-standard versions. All devices available in tape-and-
reel only.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
