T he ADM8698/ADM8699 supervisory circuits provide power  
supply monitoring and watchdog timing for microprocessor  
systems.

RESET  
T he ADM8698 monitors the 5 V VCC power supply and gener-  
ates a RESET pulse during power up, power down and during  
low voltage “Brown Out” conditions. T he RESET output is  
guaranteed to be functional (logic low) with VCC as low as 1 V.

T he ADM8699 features an identical monitoring circuit as in the  
ADM8698, plus an additional watchdog timer input to monitor  
microprocessor activity. T he RESET output is forced low if the  
watchdog input is not toggled within the 1 second watchdog  
timeout period.  
*ADM8699 ONLY  
Both parts are available in 8-pin plastic DIP/SOIC and 16-lead  
SOIC packages. T he 16-lead SOIC contains additional out-  
puts RESET (without inversion) and Watchdog Output WDO  
(ADM8699 only).
