    • A motor driving circuit has a driving controlling signal generating circuit that controls a driver with a driving controlling signal, the driver supplying a driving voltage that drives the motor to the motor. The motor driving circuit has a mode selecting circuit that detects a power supply voltage supplied from a power supply to the driver, outputs a normal operation mode signal indicative of a normal operation to the driving controlling signal generating circuit if the power supply voltage is equal to or higher than a preset first threshold, and outputs a test operation mode signal indicative of a test operation to the driving controlling signal generating circuit if the power supply voltage is lower than the first threshold.
