STM632x, STM682x 5-pin supervisor with watchdog timer and push-button reset - production data 627/ 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) - Ro HS pliance Lead-free ponents are pliant with the Ro HS directive Description 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). 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.
