    Takao,

    What Watchdog period are you looking for? Typically, the fixed Watchdog devices will be more accurate than the adjustable Watchdog devices because of the capacitor used to program the watchdog period.

    TPS3123/4, TPS3128 for lower voltage options (1.8V and lower) and TPS3820/8, TPS3823/4 for above 1.8V are good Watchdog devices with fixed Watchdog periods.

    Please provide more details about the application so I can help you find the right part. Thanks!
