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.
