Abstract
The present disclosure provides a control device having versatility and extensibility of a load driving circuit. A control device includes a processor and an IC, in which the IC includes: a communication circuit that transmits a control signal from the processor; a first drive circuit that drives a first load; a second drive circuit that drives a second load and is provided outside the IC separately from the first drive circuit; and a third drive circuit that controls the second drive circuit, the processor transmits channel information corresponding to the number of switches of the second drive circuit to the IC, and the communication circuit changes the number of channels of the third drive circuit on the basis of the channel information.
