Description

The SLG7WD47674 is a pin-selectable watchdog timer designed to monitor microprocessor activity and detect abnormal system behavior by requiring routine toggling of the watchdog input (WDI) within a specified timeout period. If the microprocessor fails to provide a valid WDI transition, the IC generates a watchdog output (WDO) signal to reset the system or trigger an interrupt, ensuring reliability. This watchdog timer offers flexible timing options, including startup delay, customizable timeout periods, and open-drain output timing (200ms), making it adaptable to various system timing requirements.
