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