CAT1232LP/CAT1832

5V and 3.3V Supply Monitor, Watchdog Timer,

Manual Reset, with Active High & Low Resets

FEATURES

DESCRIPTION

ꢀ Selectable reset voltage tolerance

— CAT1232LP for 5V supply

— CAT1832 for 3.3V supply

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 micro-

processor reset switch. The devices are drop in

replacements for the Maxim/Dallas Semiconductor

DS1232LP and DS1832 supervisors

ꢀ Selectable watchdog period:

150ms, 600ms or 1.2 sec

ꢀ Two reset outputs

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

selectabletolerancelimits, boththeRESETandRESET

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.

— 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

APPLICATIONS

ꢀ Microprocessor Systems

ꢀ Portable Equipment

ꢀ Controllers

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.

ꢀ Single Board Computers

ꢀꢀ Instrumentations

A debounced manual reset input activates the reset

outputs and holds them active for a minimum period of

250ms after being released.

ꢀ Telecommunications

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 1.2sec. 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.

For Ordering Information details, see page 11.
