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.

Note: Although this IC has electrostatic protection circuit, damage may still occur if very high electrostatic
potentials are applied.
Note: When this IC is soldered in the solder-reflow process, be sure to maintain the reflow furnace at the
curve shown in “Fig. 3–5 Reflow Furnace Temperature Curve” of DATA BOOK. This IC cannot
be exposed to the high temperature of the the solder dipping.
