An address control circuit includes a setting terminal connectable to a ground potential, a time constant setting circuit connected to the setting terminal, and a control unit connected to the time constant setting circuit and configured to set an address for serial communication. The time constant setting circuit includes a resistive element disposed between the setting terminal and the control unit and configured to protect the control unit against overvoltage. The control unit outputs a voltage to the time constant setting circuit, and sets an address at a predetermined timing based on the voltage input from the time constant setting circuit when a predetermined time has passed after the output of the voltage is stopped.

Address control circuit capable of setting address rapidly and method of setting address after power-on reset, the address control circuit providing protection against over-voltage
