TI TPS3430WDRCR

The TPS3430 is an independent window watchdog timer with a programmable watchdog window and programmable watchdog reset delay, suitable for a variety of applications. The TPS3430 window watchdog can achieve a timing accuracy of 2.5% (typical value at 25°C). Moreover, the watchdog output (WDO) reset delay can be set through the factory-programmed default delay settings or programmed via an external capacitor. During the development process or power-up, the monitor can be disabled through the SET pin to avoid unnecessary monitor timeouts. The TPS3430 comes in a small 3.00mm × 3.00mm 10-pin VSON package.
