Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF by setting the EN/ENB pin to a low or high level. The pin is internally pulled up to VIN.

What is the output configuration?

The output type is N-channel open drain, which goes low when the detected voltage falls below the threshold.
