Abstract
A motor driving apparatus includes a first driving control circuit (an MCU, a driving circuit, an input circuit, a power management IC) and a second driving control circuit (an MCU, a driving circuit, an input circuit, a power management IC). The first driving control circuit and the second driving control circuit are configured to drive a corresponding winding group of winding groups of a motor, and have a master mode for outputting a synchronous trigger signal in synchronization with driving of the corresponding winding group and a slave mode for synchronizing the driving of the corresponding winding group with an input synchronous trigger signal. When an error has occurred in an operation of the first driving control circuit in the master mode, the second driving control circuit switches an operation mode of the second driving control circuit from the slave mode to the master mode.
