Advanced Analog Technology, Inc. May 2008 AAT602 Product information presenting is current as of publication date. Details are subject to change without notice. HIGH-PRECISION RESET VOLTAGE DETECTOR FEATURES EATURES Low Current Consumption (3µA typical, VDD =3V) High-Precision Reset Voltage ±2% Hysteresis Voltage 5% Typical Reset Voltage 1.8V to 5.5V Fixed or Adjustable Delay Time Open Drain or Push-Pull Output External Delay Time SC82AB (SOT343), SOT23-5 (SOT25) Package Available GENERAL GENERAL DESCRIPTION The AAT602 is a reset voltage detector that provides a high-precision output signal, which allows users to initiate or reset the system. The detection voltage with an accuracy of ±2% is trimmed to customized specification. Delay time can be adjusted by an external capacitor. And output signal may be configured as either open drain or push-pull. With minimal external components required, the AAT602 offers a simple and economical solution.
