SOT23, Low-Power µP Supervisory Circuits  
with Battery Backup  
1–MAX364  
General Description  
Features  
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.  
o Low +1.2V Operating Supply Voltage  
(V  
or V  
)
CC  
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  
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).  
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

Note: These parts offer a choice of reset threshold voltages.  
From the table below, 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 minimum on the SOT package (tape-and-reel only).  
Devices are available in both leaded and lead-free packaging.  
Specify lead-free by replacing "-T" with "+T" when ordering.
