PCF1252-6 - Threshold detector and reset generator

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

Key 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.
