It asserts an active-low, open-drain reset output when the monitored voltage drops below that threshold, and releases it after an adjustable/selectable timeout once the rail recovers. This part is designed for systems where a clean, reliable power-on reset is needed for MCUs, DSPs, or FPGAs, especially on low-voltage core supplies.
The reset timeout is adjustable or selectable via an external capacitor on the CT pin. The exact range depends on the capacitor value; the datasheet provides the formula and typical values. This lets you tune the power-up delay to match the settling time of your supply rail or the release timing of other supervisors in the sequence.
