MITSUBISHI SEMICONDUCTOR (LSI) M63022FP SPINDLE MOTOR AND 5CH ACTUATOR DRIVER DESCRIPTION This M63022FP is 1 chip driver IC for spindle motor and 5 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,Focus/Tracking and Loading) , and three voltage supply can be set separately.
Further more this IC has short braking select function,FG amplifier, thermal shut down circuit, standby circuit, reverse rotation detect circuit.
