Product details

3.3V rail watchdog — what the threshold means for your BOM

Active-low, open-drain output can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail.

For production BOM planning, this means no forced redesign in the near term, though it is always wise to monitor PCNs for package or wafer-fab changes.
