MIC1832 µP Supervisory Circuit  
MIC1832  
µP Supervisory Circuit  
Pin Configuration  
Description  
The MIC1832 is a multifunction circuit which monitors  
microprocessor activity, external reset and power  
supplies in microprocessor based systems. The circuit  
functions include a watchdog timer, power supply  
monitor, microprocessor reset, and manual pushbutton  
reset input.  
Top View  
The power supply line is monitored with a comparator  
and an internal voltage reference. RST is forced low  
when an out-of-tolerance condition exists and remains  
asserted for at least 250ms after V  
rises above the  
CC  
threshold voltage (2.55V or 2.88V). The RST pin will  
remain logic low with V as low as 1.4V.

MIC1832M - 8 Lead Plastic SOIC Package  
The Watchdog input (ST) monitors µP activity and will  
assert RST if no µP activity has occurred within the  
watchdog timeout period. The watchdog timeout period  
is selectable with a nominal periods of 150, 600, or  
1200 milliseconds.
