Description
The SLG7WD47666 watchdog timer ensures microprocessor reliability by monitoring system behavior and triggering a reset or interrupt if anomalies are detected. The timer resets when the watchdog input (WDI) toggles within a set timeout, and a failure to do so triggers a corrective pulse. With low power consumption, a compact 1.0mm x 1.2mm STQFN package, and an enable pin (nEN) for toggling functionality, this device is ideal for small, power-sensitive applications requiring robust supervision.
