The S-801 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. Three delay times 50 ms, 100 ms,
and 200 ms are available. Two output forms, Nch open-drain and CMOS output, are available.
