What this supervisor does
The MAX16058ATA22+T from Analog Devices is a simple reset/power-on reset supervisor that monitors a single voltage rail and asserts a reset signal when the supply drops below the threshold. The reset output is active low and open-drain or open-collector, so it can be wire-ORed with other reset sources or pulled up to a different logic voltage. The reset timeout is adjustable or selectable via an external capacitor, giving the designer control over the hold time after the rail returns.
Lifecycle and sourcing posture
That means you can qualify it into a new BOM without worrying about a sudden discontinuation.
