<p>A start circuit for starting and restarting a main circuit (20) when the main circuit is started and abnormally operated comprises a start signal supply means (11) which supplies a stop signal for stopping the action of the main circuit when a standby signal is at a standby level and supplies a start signal to a circuit start node (22) of the main circuit and stops the supply of the stop signal when the standby signal changes from the standby level to a start level, a start control means (12) for stopping the supply of a start signal to the start signal supply means when the voltage of the voltage monitor node (21) of the main circuit (20) reaches a predetermined value in a start level state of the standby signal, and a restart signal generating means (13) for supplying a restart signal to the circuit start node (22) of the main circuit (20) when the voltage of the voltage monitor node (21) of the main circuit fluctuates to an abnormal value in a start level state of the standby signal.</p> |
