SLG7WD47674 - Pin-Selectable Watchdog Timer

General Description

6 3.

Specifications 7 3.1 Absolute Maximum Ratings 7 3.2 Electrical Specifications 7 4.

Typical Application Circuit 10 5.

Key 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 time.

SLG7WD47674 Pin-Selectable Watchdog Timer Datasheet The SLG7WD47674 watchdog timer with pin-selectable 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.
