M63021FP - SPINDLE MOTOR AND 5CH ACTUATOR DRIVER

Key Features

  • This IC 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,.
