Watchdog timers, both internal and external, are critical in ensuring systems never freeze or get caught in an endless loop A watchdog timer’s job is to force an embedded processor or microcontroller ...

The MAX6369–MAX6374 are pin-selectable watchdog timers that supervise microprocessor (µP) activity and signal when a system is operating improperly. During normal operation, the microprocessor should ...

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 ...
