HIGH-PRECISION VOLTAGE DETECTOR WITH A
BUILT-IN DELAY CIRCUIT
S-801 Series
The S-801 Series is a high-precision voltage detector with a built-in delay
time generater 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 for a fixed time
with no external attachment part. Three delay times, 50 ms typ., 100ms
typ., or 200 ms typ. are available. Two output types, Nch open-drain and
CMOS output, are available.
