S-801 Series ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (INTERNAL DELAY TIME SETTING) www.sii-ic.com SII Semiconductor Corporation, 2000-2016 Rev.4.2 00 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. Features Ultra-low current consumption 1.3 A typ. (at V =3.5 V) DD High-precision detection voltage 2.0 % Operating voltage range 0.95 V to 10.0 V Hysteresis characteristics 60 mV typ. Detection voltage 2.2 V to 6.0 V (0.1 V step) Three delay times A type 50 ms typ. B type 100 ms typ. C type 200 ms typ.
