SOT23, Low-Power µP Supervisory Circuits  
with Battery Backup  
General Description  
Features  
The MAX6361/MAX6363/MAX6364 supervisory circuits  
reduce the complexity and number of components  
required for power-supply monitoring and battery control  
functions in microprocessor (µP) systems. The circuits sig-  
nificantly improve system reliability and accuracy com-  
pared to that obtainable with separate ICs or discrete  
components. Their functions include µP reset, backup-  
battery switchover, and power failure warning.  
Low +1.2V Operating Supply Voltage  
(V  
CC  
or V  
)
BATT  
Precision Monitoring of +5.0V, +3.3V, +3.0V, and  
+2.5V Power-Supply Voltages  
Debounced Manual Reset Input (MAX6361)  
Battery-On Output Indicator (MAX6363)  
Auxiliary User-Adjustable RESET IN (MAX6364)  
Three Available Output Structures  
Push-Pull RESET, Open-Drain RESET,  
Push-Pull RESET  
RESET/RESET Valid Down to 1.2V Guaranteed  
The MAX6361/MAX6363/MAX6364 operate from supply  
voltages as low as +1.2V. The factory preset reset  
threshold voltage ranges from 2.32V to 4.63V (see  
Ordering Information). These devices provide a manual  
reset input (MAX6361), battery-on output (MAX6363),  
and an auxiliary adjustable reset input (MAX6364). In  
addition, each part type is offered in three reset output  
versions: an active-low push-pull reset, an active-low  
open-drain reset, and an active-high push-pull reset  
(see Selector Guide at end of data sheet).

Note: These parts offer a choice of reset threshold voltages.  
From Table 1, select the suffix corresponding to the desired  
threshold voltage and insert it into the part number to complete  
it. When ordering from the factory, there is a 2500-piece mini-  
mum on the SOT package (tape-and-reel only).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional  
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to  
absolute maximum rating conditions for extended periods may affect device reliability.

Applications Information  
In a brownout or power failure, it may be necessary to  
preserve the contents of the RAM. With a backup bat-  
tery installed at BATT, the MAX6361/MAX6363/  
MAX6364 automatically switch the RAM to backup

These devices require two conditions before switching

Many µP-based products require manual reset capabili-

This input can be driven with TTL/CMOS logic levels or  
with open-drain/collector outputs. 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 the device  
is used in a noisy environment, connect a 0.1µF capaci-  
tor from MR to GND to provide additional noise immunity.

threshold by the magnitude indicated (reset threshold  
overdrive). The graph shows the maximum pulse width

Reset In (MAX6364 only)  
RESET IN is compared to an internal 1.235V reference.  
If the voltage at RESET IN is less than 1.235V, reset is  
asserted. The RESET IN comparator may be used as  
an undervoltage detector to signal a failing power sup-  
ply. It can also be used as a secondary power-supply  
reset monitor.

Reset Output  
A µP’s reset input starts the µP in a known state. The  
MAX6361/MAX6363/MAX6364 µP supervisory circuits  
assert a reset to prevent code-execution errors during  
power-up, power-down, and brownout conditions.  
RESET is guaranteed to be a logic low or high depend-  
ing on the device chosen (see Ordering Information).
