GENERAL DESCRIPTION
Low Current Consumption
The AAT602 is a reset voltage detector that provides a
(3µA typical, VDD =3V)
high-precision output signal, which allows users to
High-Precision Reset Voltage ±2%
initiate or reset the system.
Hysteresis Voltage 5% Typical
The detection voltage with an accuracy of ±2% is
Reset Voltage 1.8V to 5.5V
trimmed to customized specification. Delay time can be
Fixed or Adjustable Delay Time
adjusted by an external capacitor. And output signal may
Open Drain or Push-Pull Output
be configured as either open drain or push-pull.
External Delay Time
With minimal external components required, the AAT602
SC82AB (SOT343), SOT23-5 (SOT25)
offers a simple and economical solution.
