Part Number : PCF1252-X
Function : Threshold detector and reset generator
Package : DIP, SO 8 Pin Type
Maker : Philips Electronics
Pinouts : 
Description :
The PCF1252-X 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 aPOWF (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 external capacitor (CCT).
A second comparator (comparator 2) has been included to enable the possibility of a second monitoring point in the system.
Features
1. Very low current consumption, typically 10 mA
2. 10 factory programmed threshold voltages available covering trip voltages from 4.75 to 2.55 V
3. ±50 mV trip point accuracy over full temperature range
4. Variable RESET delay
5. RESET pulse polarity selection
