UNISONIC TECHNOLOGIES CO., 88CXX CMOS IC www.unisonic.com.tw 1 Copyright © 2005 Unisonic Technologies Co., QW-R502-040,A BUILT-IN DELAY CIRCUIT HIGH-PRECISION VOLTAGE DETECTOR „ DESCRIPTION The UTC 88CXX series is a high-precision voltage detector developed and foundry using CM OS process. The detection voltage is fixed internally, with an accuracy of ±2.0%. The CMOS output is available. Besides, 88CXX can easily delay a release signal by attachment of an external capacitor with built-in delay circuit. „ FEATURES * High-precision detection voltage: ±2.0% * Hysteresis characteristics: 5% typ * Ultra-low current consumption satisfied various detection voltage, 1.0DŽA typ. (V œ1.5V. * Available detection voltage from 1.1~6.0V and step by 0.1V. * Low operating voltage based on detection voltage, 0.8~6.0V for for ›1.4V and 0.95~10V for œ1.5V. * Delay time setting by an additional external capacitor. SOT-25 *Pb-free plating product number: 88CXXL „ PIN CONFIGURATION PIN NO. PIN NAME
