SOT23, Low-Power μP Supervisory Circuits
with Battery Backup
General Description
The MAX6361–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 significantly
improve system reliability and accuracy compared to that
obtainable with separate ICs or discrete components.
Their functions include μP reset, backup battery
switchover, and power failure warning.
The MAX6361–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),
watchdog timer input (MAX6362), 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 open-drain reset, an
active-low open-drain reset, and an active-high open-
drain reset (see Selector Guide at end of data sheet).
Features
o Low +1.2V Operating Supply Voltage
(V CC or V BATT )
o Precision Monitoring of +5.0V, +3.3V, +3.0V, and
+2.5V Power-Supply Voltages
o Debounced Manual Reset Input (MAX6361)
o Watchdog Timer with 1.6s Timeout Period
(MAX6362)
o Battery-On Output Indicator (MAX6363)
o Auxiliary User-Adjustable RESET IN (MAX6364)
o Three Available Output Structures
Push-Pull RESET , Open-Drain RESET ,
Open-Drain RESET
o RESET/ RESET Valid Down to 1.2V Guaranteed
(V CC or V BATT )
o Power-Supply Transient Immunity
o 150ms (min) Reset Timeout Period
o Small 6-Pin SOT23 Package
