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
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.
