Watchdog Power Supply

A Watchdog Power Supply (WDPS) is useful for systems that run continuously as a WDPS will automatically reboot the system if it stalls, stops or crashes. The WD is "kicked" every few seconds with a CPU generated pulse. If the pulse is missing (CPU has crashed) the power is recycled. A cold reboot is often the most effective way to recover from software bugs, power glitches, USB stack errors or any other problem that causes the program to halt. To use this WDPS just have it supply the 5VDC to your CPU and have the CPU provide a periodic pulse to the WD. Read Moreā€¦
