... DESCRIPTION This M63015FP 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 current control drive system for Focus,Tracking, Spindle and Slide channel drive, also has a direct PWM control system for Spindle and Slide channels drive due to reducing IC power dissipation ...
