88CXXG-AF5-R

UNISONIC TECHNOLOGIES CO., LTD 88CXX BUILT-IN DELAY CIRCUIT HIGH-PRECISION VOLTAGE DETECTOR 4 CMOS IC DESCRIPTION The UTC 88CXX series are highly accurate, low power consumption voltage detector, manufactured using CMOS process. The detection voltage is fixed internally, with an accuracy of ±2.0%. Besides, UTC 88CXX can easily delay a release signal by attachment of an external capacitor with built-in delay circuit. 5 3 1 2 FEATURES * Highly accurate : 2.0% * Hysteresis characteristics: 5% typ. * Ultra-low current consumption: 1.0μA typ. (VDD=2.0V) * Detection voltage ranges: 1.5~6V and step by 0.1V. * Low operating voltage based on detection voltage * Delay time setting by an additional external capacitor.
