CMOS VOLTAGE DETECTOR
s DESCRIPTION
The SCI7700YSeries/SCI7701YSeries are a series of low-power precision voltage detectors, which do
not require external adjustments. The SCI7700YSeries/SCI7701YSeries have such applications as
battery-life detection, power supply fault monitoring, over/under-voltage protection and battery back-up
switching. The SCI7700YSeries is an open-drain Nch output type and the SCI7701YSeries is a CMOS
output type. Both are available in SOT 89-3pin (plastic) packages.
