This idea describes a new concept that utilizes two watchdog timers instead of the typical single watchdog timer found in most embedded systems. One watchdog is the typical hardware ...

Thanks to its uniquely minimized design, our Watchdog Timer easily fits into any embedded system with limited space. Best of all, it already comes with a built-in logger.

A System Monitor–The Watchdog Timer For quite some time now, the role of a system monitor in embedded systems has been fulfilled by a simple piece of logic called the Watchdog.

Embedded-system applications use WDTs (watchdog timers) to identify error conditions that cause the controller or processor to default into an erroneous state. Stand-alone WDTs used to be quite ...

The circuit in Figure 1 uses two LMC555 timers that delay a hardware reset in order to save valuable system data. It employs the microprocessor’s dedicated watchdog-overflow pin, —WDOVF, and ...
