PCF1252-8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.
