Product Description

The STWD100PYW83F is a Watchdog Timer Circuit has an WDI input and an WDO output. The input is used to clear the internal watchdog timer periodically within the specified timeout period. While the system is operating correctly, it periodically toggles the watchdog input. If the system fails, the watchdog timer is not reset, a system alert is generated and the watchdog output is asserted. The circuit also has an enable pin, which can enable or disable the watchdog functionality. The EN pin is connected to the internal pull-down resistor. The device is enabled if the EN pin is left floating.
