BU64253GWZ
Bi-directional VCM Driver for Autofocus

The BU64253GWZ is designed to drive Bi-directional voice coil motors. Additionally the driver is able to source the output current without the need for a direction control signal. The driver includes ISRC (Intelligent Slew Rate Control) to reduce mechanical ringing to optimize the camera’s autofocus capabilities.
