Window watchdog timer with programmable reset delay for a wide variety of applications

The TPS3430, from Texas Instruments, is a standalone window watchdog timer with programmable watchdog window and programmable watchdog reset delay for a wide variety of applications. The device window watchdog delivers 15% timing accuracy (–40C to +125C), 2.5% timing accuracy (typical at 25C) and the WDO reset delay can be set by factory-programmed default delay settings, or programmed by an external capacitor. The device can be disabled via the SET pins to bypass undesired timeouts during the development process or during power on. The device is available in a small 3mm x 3mm, 10-pin VSON package.
