| description | A technology of starting power supply from an external device to a load device in a shorter period, after detection of connection between the external device and the load device, is provided. A control device includes a first connector attachable to and detachable from an external device, a power supply path to electrically connect a load device and the first connector, a load switch to switch between connection and disconnection of the power supply path, a protection circuit to protect the load switch from an inrush current to the load switch, the protection circuit including at least a capacitor, and a control circuit. The control circuit is operable to switch the load switch from disconnection to connection after a total time of a preset set time and a first time based on a charging time of the capacitor which has elapsed since connection of the first connector to the external device was detected. |
