General Description
The MIC1232 is a multifunction circuit which monitors mi-
croprocessor activity, external reset and power supplies in
microprocessor based systems. The circuit functions include
a watchdog time, 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
rises above the threshold voltage
CC
(4.5V or 4.75V). The /RST pin will remain logic low with V
as low as 1.4V.
The Watchdog input (/ST) monitors µP activity and will as-
sert /RST if no µP activity has occurred with in the watchdog
timeout period. The watchdog timeout period is selectable
with nominal period of 150, 600, 1200 milliseconds.
