M63020FP
SPINDLE MOTOR AND 5CH ACTUATOR DRIVER
[ 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, thermal shut down circuit, standby circuit, reverse
rotation detect circuit.
