In order to provide a motor driving circuit with which the portion corresponding to a malfunctioning phase can be separated while reducing the size and the cost, this motor driving circuit, which drives a motor, is equipped with: a second driver circuit, which drives a driver circuit that supplies to a multiphase motor of three or more phases the driving current corresponding to one phase of the multiphase motor; and an electrical circuit, which has multiple electrical components, and which switches the connection relationships between these electrical components in accordance with an operating mode specified from outside of the motor driving circuit, thereby providing the circuit function corresponding to the operating mode.
