INTEGRATED CIRCUITS DATA SHEET PCF1252-X family Threshold detector and reset generator 1998 Apr 16 Product specication Supersedes data of 1996 Jan 23 File under Integrated Circuits, IC11Philips Semiconductors Product specication Threshold detector and reset generator PCF1252-X family FEATURES GENERAL DESCRIPTION Very low current consumption, typically 10 A The PCF1252-Xs are low-power CMOS voltage threshold detectors designed especially for supervision of 10 factory programmed threshold voltages available microcontroller/microprocessor systems for detection of covering trip voltages from 4.75 to 2.55 V power-on/off conditions and generation of a system reset 50 mV trip point accuracy over full temperature range pulse. The PCF1252-X also provides a POWF (power fail) Variable RESET delay output which is activated at a precise factory-programmed trip point. A system RESET output has a built-in delay with RESET pulse polarity selection duration determined by an external capacitor (C ). CT Defined outputs at 0.6 V (typ.) A second comparator (comparator 2) has been included to Comparator for second level detection enable the possibility of a second monitoring point in the (e.g. overvoltage detection) system. Advance warning of power fail Operating temperature range - 40 to +85 C.
