It belongs in office equipment, consumer electronics, telecom indoor racks, and test gear — not in a motor drive enclosure or under-hood automotive bay.
No last-time-buy risk, no PCN for obsolescence on the horizon.
The reset timeout is 140 ms minimum. This is the guaranteed hold time after VCC rises above the threshold before the reset outputs release.
It monitors a single voltage — one channel, one threshold at 4.4 V for a 5 V rail.
