PCF1252-2 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...
