1 UNISONIC TECHNOLOGIES CO., LTD 88NXX BUILT-IN DELAY HIGH-PRECISION OLTAGE ECTOR DESCRIPTION The UTC 88NXX is a high-precision voltage detector developed basing on CMOS technology. The detection voltage is fixed internally. A time delayed reset can be accomplished with an external capacitor. N-ch open-drain output form is available. The UTC 88NXX is generally used for power supply monitor of portable equipment such as notebook PCs, digital still cameras, PDAs, and mobile phones, constant voltage power monitor of cameras, video equipment and communication equipment, and power monitor or reset of CPUs and microcomputers. FEATURES * Extremely Low Current Dissipation : 1.2μA Typ. (Detection oltage DD =3.5 ) * ±2.0 % Accuracy Detection oltage * Hysteresis Characteristics: 5% TYP * Detection oltage varies from 1.5 to 6.0 with 0.1 step * Output Forms: N-ch open-drain output (when it is in Active-Low) ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing 88NXXL-AD4-R 88NXXG-AD4-R SOT-143 Tape Reel 88NXXL-AF5-R 88NXXG-AF5-R SOT-25 Tape Reel Note: XX: Output oltage, refer to Marking Information. 1 of 8 Copyright 2018 Unisonic Technologies Co., Ltd
