Bi-directional VCM Driver for Autofocus
BU64253GWZ
General Description
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.
