FUNCTIONAL DIAGRAM
DESCRIPTION
The CAT1232LP and CAT1832 microprocessor
supervisors can halt and restart a “hung-up” or
“stalled” microprocessor, restart a microprocessor
after a power failure, and debounce a manual/push-
button microprocessor reset switch. The devices are
drop
in
replacements
Semiconductor DS1232LP and DS1832 supervisors
for
the
Maxim/Dallas
Precision reference and comparator circuits monitor
the 5V or 3.3V system power supply voltage, V
CC
.
During power-up or when the power supply falls
outside selectable tolerance limits, both the RESET
and ˉˉˉˉˉˉ become active. After the power supply
voltage rises above the RESET threshold voltage, the
reset signals remain active for a minimum of 250ms,
allowing the power supply and system processor to
stabilize. The trip-point tolerance input, TOL, selects
the trip level tolerance to be either 5% or 10% for the
CAT1232LP 5V supply and 10% or 20% for the
CAT1832 3.3V supply.
Each device has a push-pull, active HIGH reset
output. The CAT1232LP also has an open drain,
active LOW reset output while the CAT1832 also has
a push-pull, active LOW reset output.
A debounced manual reset input activates the reset
outputs and holds them active for a minimum period of
250ms after being released.
Also included is a watchdog timer to reset a
microprocessor that has stopped due to a software or
hardware failure. Three watchdog time-out periods are
selectable: 150ms, 600ms and 1.2s. If the ˉˉ input is
not strobed low before the watchdog time out period
expires, the reset signals become active for a
minimum of 250ms.
