Abstract: A control circuit includes a current supply, a voltage limitation circuit, a current limitation circuit, and a voltage control stop circuit. The current supply circuit supplies a current to a subject to be controlled. The voltage limitation circuit limits a voltage applied to the subject to be controlled to a predetermined range by controlling the current in the current supply circuit. The current limitation circuit limits the current in the current supply circuit when the current in the current supply circuit is an overcurrent. The voltage control stop circuit stops the voltage limitation circuit to run when the current in the current supply circuit is the overcurrent.
