ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR
WITH DELAY CIRCUIT (INTERNAL DELAY TIME SETTING)
S-801 Series
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.
