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.
