Watchdog circuit and electronic equipment

The utility model provides a watchdog circuit and electronic equipment, the watchdog circuit comprises a timing circuit and a level conversion circuit, and the timing circuit is used for connecting a main control circuit and outputting a holding signal or a reset signal according to the condition of a reset signal sent by the main control circuit. The level conversion circuit is connected with the timing circuit and the main control circuit, and can receive a first indication signal used for indicating that the main control circuit is not in a burning state, or receive a second indication signal used for indicating that the main control circuit enters the burning state. And the level conversion circuit is used for outputting a holding control signal to the main control circuit when receiving the holding signal and the first indication signal or receiving the reset signal and the second indication signal so as to indicate the main control circuit to keep normal work. The watchdog circuit enables the main contr
