PCF1252-7 Datasheet Threshold detector and reset generator

Manufacturer: NXP Semiconductors

General Description

plastic dual in-line package;

8 leads (300 mil) PCF1252-X family GENERAL DESCRIPTION The PCF1252-Xs are low-power CMOS voltage threshold detectors designed especially for supervision of microcontroller/microprocessor systems for detection of power-on/off conditions and generation of a system reset pulse.

The PCF1252-X also provides a POWF (power fail) output which is activated at a precise factory-programmed trip point.
