SLG7WD47674 Datasheet | Renesas

features is designed to monitor microprocessor (μP) activities and identify abnormal system behavior. To confirm that the code is being processed appropriately, the microprocessor should routinely toggle the watchdog input (WDI) before the selected watchdog timeout length expires. The supervisor initiates a watchdog (WDO) output signal to indicate that the system is not executing the intended instruction within the allotted time if the μP does not provide a valid watchdog input transition before the timeout period ends. When there are processing issues, this watchdog output pulse can be used to either reset the μP or cause a system interrupt to notify of errors. By identifying mistakes in code execution, the SLG7WD47674 provides flexible watchdog timer supervision, improving system reliability. This IC meets a variety of system timing needs by offering numerous pin-selectable watchdog timing options: - Watchdog startup delay: before the watchdog timer starts, there is a little delay. - Watchdog timeout period: specifies how long the watchdog timeout usually lasts after the first startup delay. - Watchdog output/timing options: open-drain (200 ms). This is a pre-configured device. The configuration of this device can be modified to meet specific requirements at no additional NRE costs. Other functions and features may also be added.
