TYPICAL APPLICATION CIRCUIT
GENERAL DESCRIPTION
The ADM698/ADM699 supervisory circuits provide power
+5V
supply monitoring and watchdog timing for microprocessor
systems.
The ADM698 monitors the 5 V V CC power supply and gener-
ates a RESET pulse during power up, power down and during
low voltage “Brown Out” conditions. The RESET output is
guaranteed to be functional (logic low) with V CC as low as 1 V.
The ADM699 features an identical monitoring circuit as in the
ADM698 plus an additional watchdog timer input to monitor
microprocessor activity. The RESET output is forced low if the
watchdog input is not toggled within the 1 second watchdog
timeout period.
Both parts are available in 8-pin plastic DIP and 16-lead SOIC
packages. The 16-lead SOIC contains additional outputs
RESET (without inversion) and Watchdog Output WDO
(ADM699 only).
