This IC is 1 chip driver IC for spindle motor and 4 channel actuators. All of the motor and actuator of optical disk drive system (CD-ROM etc.) can be drived by only this IC.

This IC has a direct PWM control system for Spindle and Slide channels drive due to reducing IC power dissipation.

This IC has three voltage supply terminals (for Spindle, Slide/Loading and Focus/Tracking) , and these voltage supply can be set separately.

Further more this IC has FG amplifier, thermal shut down circuit, standby circuit, channel select function, reverse rotation detect circuit.
