S-809xxC Series ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) www.sii-ic.com Seiko Instruments Inc., 2001-2015 Rev.4.1 00 The S-809xxC Series is a high-precision voltage detector developed using CMOS process. The detection voltage is fixed internally with an accuracy of 2.0 %. A time delayed reset can be accomplished with the addition of an external capacitor. Two output forms, Nch open-drain and CMOS output, are available. Features Ultra-low current consumption 1.0 A typ. (Detection voltage 1.4 V, at V =2.0 V) DD 1.1 A typ. (Detection voltage 1.5 V, at V =3.5 V) DD High-precision detection voltage 2.0 % Operating voltage range 0.7 V to 10.0 V Hysteresis characteristics 5 % typ. Detection voltage 1.3 V to 6.0 V (0.1 V step) Output forms Nch open-drain output (Active Low) CMOS output (Active Low) *1 Lead-free, Sn 100%, halogen-free *1.
