PCF1252-8

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.

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.)
  • Advance warning of power fail
  • Operating temperature range -40 to +85 °C. - X = 0 to 9; depending on threshold voltage. PCF1252-X family
