T he ADM8698/ADM8699 supervisory circuits provide power
supply monitoring and watchdog timing for microprocessor
systems.
T he ADM8698 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. T he
RESET
output is
guaranteed to be functional (logic low) with V
CC
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.
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).
