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.
s 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)
