In this application note, the watchdog timer is operated using the system clock. An LSI incorporates the watchdog timer (WDT). The WDT is an 8-bit timer that can generate an internal reset signal if a ...
Most watchdog-timer ICs produce a single limited-duration output pulse when the watchdog timeout expires. Some applications, however, require the output to latch. This simple circuit provides a ...
For those embedded systems that can’t be constantly watched by a human, watchdog timers may be the solution. Most embedded systems need to be self-reliant. It’s not usually possible to wait for ...
To protect your device against potentially hazardous uncontrolled ac or dc power, you may want to consider a watchdog timer. A watchdog timer monitors activity; if no activity occurs within a preset ...
With the prevalence of microcontrollers (MCUs) as processing units in safety-related systems (SRS) comes the need for diagnostic measures that will ensure safe operation. IEC 61508-2 specifies ...
