CMD5954
Description
The CMD5954 is a 4-channel BTL driver IC for
driving the motors and actuators in products
such as CD-ROM/DVD-ROM/DVD-Player
drives. Two of the channels use current feedback
to minimize the current phase shift caused by the
influence of load inductance.
Applications
CD-ROM drives, DVD drives, DVD-ROM
drives.
