Product details

5V rail supervisor with a 170 ms reset hold

It holds the reset output low for a minimum of 170 ms after the supply recovers, giving the system time to stabilize before the processor or logic starts executing code.

Open-drain output for wired-OR or level translation

The reset output is open-drain, active low, which lets you pull it up to a different voltage than the monitored rail — useful when the supervisor runs at 5V but the downstream microcontroller operates at 3.3V. The open-drain stage also allows multiple supervisors to share a common reset line in a wired-OR configuration.
