MITSUBISHI SEMICONDUCTOR (LSI)
M63015FP
SPINDLE MOTOR AND 4CH ACTUATOR DRIVER
DESCRIPTION
This M63015FP 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 current control drive system for Focus,Tracking,
Spindle and Slide channel drive, also 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 an operational amplifier for Slide input,
FG amplifier, thermal shut down circuit, standby circuit, channel
select function, reverse rotation detect circuit and Short braking
select.
APPLICATION
CD-ROM, DVD, DVD-ROM, DVD-RAM ,Optical disc related
system, etc.
