2.64V threshold supervisor for 3.3V rails
The active-low, open-drain output keeps the downstream processor or logic in reset until the supply has been above the threshold for the 10ms minimum timeout period. This part is designed for 3.3V nominal rails where a 2.64V threshold provides a clean brownout detection window before the core logic loses state.
Active low, open-drain output — reset polarity and pull-up
The reset output is active low, meaning the output goes low when the monitored voltage falls below the threshold and stays low through the timeout period after recovery. This output topology allows the reset signal to be shared with other open-drain devices on the same line without contention.
