ACE302A
Low Voltage Detector with Built-in Delay Circuit
Description
The ACE302A Series is a series of high-precision voltage detectors with a built-in delay time generator of
fixed time. developed using CMOS process.
The detection voltage is fixed internally, with an accuracy of ±2.0%. Internal oscillator and counter timer
can delay the release signal without external parts, delay times 210 ms Two output forms, NMOS
open-drain and CMOS output are available.
Features
