ASM1232LP - 5V uP Power Supply Monitor and Reset Circuit

Datasheet Summary

Description

The ASM1232LP/LPS is a fully integrated microprocessor supervisor.

It can halt and restart a “hung-up” microprocessor, restart a microprocessor after a power failure.

It has a watchdog timer and external reset override.

Features

  • 5V supply monitor Selectable watchdog period Debounce manual push-button reset input Precision temperature-compensated voltage reference and comparator. Power-up, power-down and brown out detection 250ms minimum reset time Active LOW open drain reset output and active HIGH push-pull output Selectable trip point tolerance: 5% or 10% RESET - RESET PBRST TD Push Button Debounce Voltage Sense Comparators Watchdog Tr.
