Watchdog Timers, STMicroelectronics


Watchdog timers are standalone devices that can trigger a high priority interrupt on the microcontroller or microprocessor to take an appropriate action, such as system reboot. These devices are a robust, reliable means of monitoring software code execution, or hardware failures, and require high security level of applications.

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.
