Motor driver supplying drive current while adjusting decay rate thereof










Image Number 19 for United States Patent #8129934.

A motor driver that supplies a drive current to a stepping motor includes a decay rate controller configured to mix a first decay rate and a second decay rate smaller than the first decay rate with each other, and set a plurality of mix decay rates, a control logic circuit configured to create magnetization patterns for attenuating the drive current at the mix decay rates, and a drive current output circuit configured to output the drive current to the stepping motor in accordance with the magnetization patterns.
