Microcontrollers usually requirea watchdog timer to bring highcurrents or high voltages into a safecondition. Many microcontrollers havebuilt-in watchdog timers for this purpose.You may, however, ...

The MAX6369-74 series of pin-selectable watchdog timers are designed to supervise µP activity and indicate when a system is working improperly. During normal operation, a µP should repeatedly toggle ...

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 ...

With so many cell phones, PDAs, and MP3 players using touch-sensitive keypads, wheels, and screens for user input, regular mechanical pushbuttons are beginning to seem outdated. Even so, mechanical ...

In many designs, the differentiator between a circuit that works “pretty well” and one that works “really well” is the addition of modest supervisory and support functions. It’s even better if these ...
