FEATURES  
DESCRIPTIO  
The LTC®1232 provides power supply monitoring,  
watchdog timing and external reset for microprocessor  
systems. A precise internal voltage reference and  
comparator circuit monitor the power supply line. When  
an out-of-tolerance condition occurs, the reset outputs  
are forced to active states. The RST output is guaranteed  
to remain logic low even with VCC as low as 1V.  
Guaranteed Reset Assertion at VCC = 1V  
8-Pin SO Plastic Package  
2.0mA Maximum Supply Current  
4.62V/4.37V Precision Voltage Monitor  
Power OK/Reset Time Delay: 600ms  
Minimum External Component Count  
Superior Upgrade for DS1232  
TheLTC1232hasaninternalwatchdogtimerwhichforces  
the reset outputs to active states when the Strobe input is  
not forced low prior to a preset time-out period. The  
watchdogtimingcanbesettooperateontime-outperiods  
of typically 150ms, 600ms or 1.2 seconds.

APPLICATIO S  
Critical µP Power Monitoring  
Intelligent Instruments  
Computers and Controllers  
The LTC1232 performs push-button reset control.  
The LTC1232 debounces the push-button input  
and guarantees an active reset pulse width of 250ms  
minimum.
