It asserts a reset signal when any monitored voltage falls below its threshold and holds reset for a minimum of 140 ms after all rails return above threshold. The three thresholds are 2.25 V, 2.93 V, and an adjustable channel — covering the common 2.5 V and 3.3 V logic rails plus a custom monitor point set by an external resistor divider.
Both an active-high and an active-low reset output are available, each push-pull / totem-pole.
The two parts share the same pinout, package, and reset timing. The difference is the fixed threshold voltages: the -25 variant monitors 2.25 V and 2.93 V, while the -18 variant monitors 1.68 V and 2.93 V. Choose the variant whose fixed thresholds match your core supply rails.
No. The three monitored inputs are referenced to the device ground pin. The adjustable channel can be set with a resistor divider from a positive rail, but the supervisor itself has no provision for negative-voltage sensing.
