3 Description

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.
