应用须知

  • Disabling the Watchdog Timer for TI's Family of Supervisors
    PDF, 138 Kb, 档案已发布: Oct 30, 2003
    In many microprocessor applications where a watchdog supervisor, such as the TPS3306, is required, it may be necessary to disable the watchdog. This is particularly true when software boot times exceed the watchdog time-out period. This application note describes a circuit that can be used to selectively disable the watchdog timer.
