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 Philips PCF1252-X family consists of low-power CMOS integrated circuits designed for supervising microcontroller and microprocessor systems. These devices detect voltage threshold conditions to generate system reset pulses and provide power-on/off status signals. The family offers ten versions with factory-programmed trip voltages ranging from 2.55 V to 4.75 V.
