This also lets you wire-OR multiple reset outputs together. No need to worry about thermal shutdown in a hot enclosure or cold start in a truck cab.
The ROHS3 compliance means it is ready for current lead-free assembly lines.
It has an open-drain (open-collector) output — you need an external pull-up resistor to the logic supply voltage.
Yes — the open-drain output can be pulled up to 3.3V, and the 2.188V threshold works as an undervoltage monitor on a 3.3V rail (about 66% of nominal), though it is more commonly paired with 2.5V rails.
