ILC1232

mP Supervisory Circuit

General Description

Features

• Power OK/Reset Time Delay, 250ms min.

• Watchdog Timer, 150ms, 600ms, or 1.2s typical

• Precision Supply Voltage Monitor, Select Between 5% or

10% of Supply Voltage

The ILC1232 is a multifunction circuit which monitors micro-

processor activity, external reset and power supplies in

microprocessor based systems. The circuit functions

include a watchdog timer, power supply monitor, micro-

processor reset, and manual pushbutton reset input.

• 18µA Supply Current

• Debounced External Reset Input

• 8-Pin SO Package

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_CCrises above the threshold voltage

Applications

• Computers

• Controllers

(4.5V or 4.75V). The RST pin will remain logic low with V_CC

as low as 1.4V.

• Critical Microprocessor Power Monitoring

• Intelligent Instruments

• Portable Equipment

The Watchdog input (ST) monitors mP activity and will

assert RST if no mP activity has occurred within the watch-

dog timeout period. The watchdog timeout period is selec-

table with nominal periods of 150, 600, or 1200 milliseconds.
