Reset supervisor for a single 2.25 V rail
When the monitored supply drops below that threshold, the open-drain output pulls low and holds the reset state for a minimum of 10 ms after the rail recovers. This is a straightforward supervisor — no watchdog, no manual reset input, just a clean active-low assertion on power-up or brownout.
