GENERAL D ESCRIP TIO N

T he ADM8698/ADM8699 supervisory circuits provide power

supply monitoring and watchdog timing for microprocessor

systems.

V_CC

µP POWER

µP RESET

RESET

T he ADM8698 monitors the 5 V V_CCpower 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 V_CCas 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).
