More Information

The TPS3431 is a standard programmable watchdog timer with an enable feature for a wide variety of applications. The watchdog timeout features a 15% accuracy, high-precision timing (–40°C to +125°C) and 2.5% typical at 25°C. The watchdog timeout can be programmed either by an external capacitor, or by factory-programmed default delay settings. The watchdog can be disabled via the Enable pin or the SET logic pins to avoid undesired watchdog timeouts during the development process.
