Abstract
A motor driver circuit comprising a diving circuit for driving at least one motor, a plurality of DC/DC converters, and a stopping circuit for stopping the DC/DC converter if failure is detected in an output of the DC/DC converter, wherein a first signal is outputted when a specific DC/DC converter of the plurality of DC/DC converters is stopped by the stopping circuit, and a specific DC/DC converter is recovered when a second signal is inputted. A CPU of an apparatus incorporated with the motor driver circuit is informed that the specific DC/DC converter has been stopped by the stopping circuit. Moreover, the stopped DC/DC converter can be recovered without need for turning off a power supply of the motor driver circuit itself.
