Product details

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.A system RESET output has a built-in delay with duration determined by an

Features

Very low current consumption, typically 10 µA.
10 factory programmed threshold voltages available covering trip voltages from 4.75 to 2.55 V.
±50 mV trip point accuracy over full temperature range.
Variable RESET delay.
RESET pulse polarity selection.
Defined outputs at 0.6 V (typ. ).
Comparator for second level detection (e. g. overvoltage detection).
Advance warning of power fail.
Operating temperature range.
