M63010FP
SPINDLE MOTOR AND 4CH ACTUATOR DRIVER
<FEATURES>
This IC 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 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/Loading and Focus/Tracking) , and these voltage
supply can be set separately.
Further more this IC has FG amplifier, thermal shut down
circuit, standby circuit, channel select function, reverse rotation
detect circuit.
<APPLICATION>
CD-ROM, DVD, DVD-ROM, DVD-RAM ,
Optical disc related system,etc
