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.

APPLICATION

  CD-ROM, DVD, DVD-ROM, DVD-RAM ,Optical disc related system,etc
