CAT872 Datasheet Dual Input Reset Generator

Manufacturer: onsemi

Overview: CAT871, CAT872 Dual Input Reset Generator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

CAT871, CAT872 are dual input reset generators designed to restart microprocessor and microcontroller based systems when the watchdog timer or other resetting mechanisms have bee disabled or failed.

CAT871, CAT872 monitor two inputs and output an active low reset pulse after both inputs have been active (logic low) for a factory preset minimum time.

The reset pulse width is 2.2 ms for CAT871 and 70 ms for CAT872.

Key Features
