PCF1252-2規(guī)格書詳情

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 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

? 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.)

? Comparator for second level detection

(e.g. overvoltage detection)

? Advance warning of power fail

? Operating temperature range ?40 to +85 °C.
