LTC1232

Microprocessor

Supervisory Circuits

FEATURES

DESCRIPTIO

The LTC^®1232 provides power supply monitoring,

watchdog timing and external reset for microprocessor

systems. A precise internal voltage reference and

comparator circuit monitor the power supply line. When

an out-of-tolerance condition occurs, the reset outputs

are forced to active states. The RST output is guaranteed

to remain logic low even with V_CCas low as 1V.

■

Guaranteed Reset Assertion at V_CC= 1V

■

8-Pin SO Plastic Package

■

2.0mA Maximum Supply Current

■

4.62V/4.37V Precision Voltage Monitor

■

Power OK/Reset Time Delay: 600ms

■

Minimum External Component Count

■

Superior Upgrade for DS1232

TheLTC1232hasaninternalwatchdogtimerwhichforces

the reset outputs to active states when the Strobe input is

not forced low prior to a preset time-out period. The

watchdogtimingcanbesettooperateontime-outperiods

of typically 150ms, 600ms or 1.2 seconds.

APPLICATIO S

■

Critical µP Power Monitoring

■

Intelligent Instruments

■

Computers and Controllers

The LTC1232 performs push-button reset control.

The LTC1232 debounces the push-button input

and guarantees an active reset pulse width of 250ms

minimum.
