FAQ

How is the reset delay time configured?

The reset delay time is set by connecting an external capacitor to the designated pin, allowing flexibility based on application needs.

What is the active state of the reset output?

The reset output is active low, meaning it asserts the reset signal when the detected voltage falls below the threshold.
