Description

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 case of RST). These devices also offer a watchdog timer (except for STM6322/6825) and/or a push-button (MR) reset input.

These devices are available in a standard 5-pin SOT23 package.

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.)

• Manual reset input (MR)

• Low supply current - 3 µA (typ.)

• Guaranteed RST (RST) assertion down to VCC = 1.0 V

• Operating temperature: –40 to +85 °C (industrial grade)

• RoHS compliance

Lead-free components are compliant with the RoHS directive
