The active-low, open-drain output stays low for a minimum of 65ms after the rail recovers, giving the downstream processor time to stabilise before the reset is released.
The open-drain output lets you pull up to any voltage up to the absolute maximum of the device, so it interfaces directly with 1.8V, 2.5V, or 3.3V logic without a level shifter.
The reset output is active low — it goes low when the supply drops below the threshold and stays low for the reset timeout period after the rail recovers.
The reset timeout is a minimum of 65ms. This ensures the processor has enough time to complete its power-up sequence before the reset is deasserted.
