Abstract:
A motor control circuit 1 for controlling driving of a plurality of motors is provided with a plurality of motor driver circuits 7 and 8 for controlling driving of the plurality of motors 3 and 4, a plurality of excess current detection circuits 39 and 40 each for detecting an excess current flowing through corresponding one of the plurality of motors 3 and 4 to determine which motor driver circuit among the plurality of motor driver circuits 7 and 7 caused the excess current. The motor control circuit further includes a nonvolatile memory 46 configured to receive detection results from the plurality of excess current detection circuits 39 and 40 and store information on which motor driver circuit among the plurality of motor driver circuits 7 and 8 caused the excess current.
