General Description

The ML5954 is a four-channel BTL driver IC for driving the motors and actuators in products such as

CD-ROM and DVD. Two channels use current feedback to minimize the current phase shift caused by the

influence of load inductance. The IC is used in CD-ROM drivers and DVD players.
