ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
S-809xxC Series
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.
