CMOS VOLTAGE DETECTOR

■ 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.

■ FEATURES

Many types ....................................................................see the next page

Low operating supply current..........................................Typ 1.8µA (SCI7700YNA, VDD=3.0V)

Low range of operating voltage ......................................Typ 1.2V (SCI7700YNA)

Temperature coefficient of detection voltage ..................Typ (detection voltage/reference voltage)

x 0.1 (mV/°C)

•

Hysteresis difference ......................................................Typ detection voltage x 0.05V

Package ..........................................................................SOT 89-3pin (plastic)

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.
