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
VOM4.0V(typ.) at PreVcc=12V,PVcc=5V,RL=8W
2) Level shift circuit built in.
3) Thermal-shut-down circuit built in.
4) Stand-by mode built in.
