A motor driver circuit includes a diving circuit for driving at least one motor, a plurality of DC/DC converters for respectively generating different voltages, a detection circuit to detect an output failure in the plurality of DC/DC converters, and a stopping circuit for stopping a specific DC/DC converter if failure is detected in an output of the specific DC/DC converter. In addition, a signal output circuit outputs a first signal if the specific DC/DC converter of the plurality of DC/DC converters is stopped by the stopping circuit, recovery means recovers the specific DC/DC converter when a second signal is inputted, and a reset circuit stops the rest of the plurality of DC/DC converters, if the stopping circuit stops any one of the plurality of DC/DC converters other than the specific DC/DC converter.
