CAT1232, CAT1832

5V and 3.3V Supply Monitor, Watchdog Timer,

Manual Reset, with Active High & Low Resets

FEATURES

Selectable reset voltage tolerance

— CAT1232LP for 5V supply

— CAT1832 for 3.3V supply

Selectable watchdog period:

150ms, 600ms or 1.2s

Two reset outputs

— Active high, push-pull reset output

— Active low, open-drain reset output

(CAT1232LP)

— Active low, push-pull reset output (CAT1832)

Debounced manual push-button reset

Compact SOIC and MSOP packages

For Ordering Information details, see page 11.

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 for the Maxim/Dallas

Semiconductor DS1232LP and DS1832 supervisors

Precision reference and comparator circuits monitor

the 5V or 3.3V system power supply voltage, V

During power-up or when the power supply falls

outside selectable tolerance limits, both the RESET

¯¯¯¯¯¯

and RESET 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 ST input is

not strobed low before the watchdog time out period

expires, the reset signals become active for a

minimum of 250ms.
