An apparatus and a method for driving a voice coil motor (VCM) may include an instruction signal generating unit generating an instruction signal according to a digital signal generated from an input signal, and a driving unit driving the VCM by selecting a path for a driving current applied to the VCM according to the digital signal and controlling a duty of the driving current according to the instruction signal.

Apparatus and method for driving voice coil motor

Embodiments of the invention provide an apparatus for driving a voice coil motor actuator providing a driving signal to a coil for controlling a position of a lens barrel in which a magnet is equipped. The apparatus includes a plurality of hall sensors configured to detect the position of the lens barrel in which the magnet is equipped, and a voice coil motor driving integrated circuit configured to provide the driving signal to the coil based on outputs from the plurality of hall sensors and a received target position. The plurality of hall sensors are embedded in the voice coil motor driving integrated circuit along a moving direction of the magnet.
