BA5954FP/FM is an actuator driver IC for CD-ROM

and DVD players. This actuator driver adopts current

feedback system. This IC incorporates 2 channel

actuator drivers and 2 channel motor drivers.

Current phase lag influenced load inductance is little,

because this type is current feedback.

1) Wide dynamic range

2) Level shift circuit built in.

3) Thermal-shut-down circuit built in.

4) Stand-by mode built in.
