The circuit operates on a microcontroller which has a generator that outputs a sequence of pulses (11) set by the controller. The pulses are received by the watchdog circuit (5) and have a period that is greater or less than the loop time of the watchdog circuit. The total period of the pulse sequence is greater or the same as the execution time of the microcontroller program. If the period is exceeded a reset is generated (7).
