ILC1832 1.1
The ILC1832 is a multifunction circuit which monitors micro-
processor activity, external reset and power supplies in
microprocessor based systems. Ths circuit functions
include a watchdog timer, power supply monitor, micro-
processor reset, and manual pushbutton reset input.
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
CC
rises above the threshold voltage
(2.55V or 2.88V). The RST pin will remain logic low with
V
CC
as low as 1.4V.
The Watchdog input (ST) monitors μP activity and will assert
RST if no μP activity has occurred within the watchdog time-
out period. The watchdog timeout period is selectable with
nominal periods of 150, 600, or 1200 milliseconds.
Power OK/Reset Time Delay, 250ms min.
