Description

The TPS3430 is a standalone window watchdog timer with programmable watchdog window and programmable watchdog reset delay for a wide variety of applications. The TPS3430 window watchdog achieves 2.5% timing accuracy (typical at 25°C) and the watchdog output (WDO) reset delay can be set by factory-programmed default delay settings, or programmed by an external capacitor. The watchdog can be disabled via the SET pins to avoid undesired watchdog timeouts during the development process or during power on. The TPS3430 is available in a small 3.00-mm × 3.00-mm, 10-pin VSON package.
