Standard programmable watchdog timer with enable

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.
