Description for the TPS3431
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.
The TPS3431 is available in a small 3.00-mm × 3.00-mm, 8-pin VSON package.
