The S-808xxC series is a series of high-precision voltage detectors developed using CMOS
process. The detection voltage is fixed internally with an accuracy of
±
2.0%. Two output forms, Nch open-drain and CMOS output, are available. Ultra-low current
consumption and miniature package lineup can meet demand from
the portable device applications.
