2.5V rail supervisor for industrial and automotive environments
The open-drain output can be wire-ORed with other reset outputs, making it straightforward to combine multiple supply-rail supervisors into a single reset signal for the system controller.
170ms timeout — why the minimum matters for boot reliability
The reset timeout is specified as 170ms minimum, meaning the output stays low for at least 170ms after the supply crosses the threshold on the way up. That minimum guarantees the 2.5V rail has fully settled and the oscillator has started before the processor is released from reset — a common failure point when the timeout is too short for the bulk capacitance on the rail.
