    Abstract: 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.
