DATA SHEET SCI7700/01Y Series GRAPHICS November 1996 SCI7700/01Y Series November 1996 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 ..........................................
