The MIC1832 is a multifunction circuit which monitors
microprocessor activity, external reset and power
supplies in microprocessor based systems. The circuit
functions include a watchdog timer, power supply
monitor, microprocessor 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
μ
P activity and will
assert RST if no
μ
P activity has occurred within the
watchdog timeout period. The watchdog timeout period
is selectable with a nominal periods of 150, 600, or
1200 milliseconds.
