Abstract
According to one embodiment, there is provided a control device including a drive circuit and a control circuit. The drive circuit includes a plurality of transistors and a current determination circuit. The plurality of transistors is electrically connected in parallel to each other between a first node and a second node. The first node is connected to a power supply circuit. The second node is connected to a DC motor. The current determination circuit determines a current flowing between the first node and the second node. The control circuit generates a control signal to control a number of transistors to be turned on among the plurality of transistors in accordance with the determined current. The drive circuit drives the DC motor using a current in response to the control signal.
