STM6321 5-pin supervisor

The STM6xxx supervisors are self-contained devices which provide microprocessor supervisory functions. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition. When an invalid VCC condition occurs, the reset output (RST) is forced low (or high in the cas.

STM6321 Features

* Precision VCC monitoring of 5, 3.3, 3, or 2.5 V power supplies

* RST outputs (active low, push-pull or open drain)

* RST outputs (active high, push-pull)

* Reset pulse width of 1.4 ms, 200 ms and 240 ms (typ.)

* Watchdog timeout period of 1.6 s (typ.)
