STM6822 Overview
The STM6xxx supervisors are self-contained devices which provide microprocessor supervisory functions. A precision voltage reference and parator 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).
STM6822 Key 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
- 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)
