M63013FP
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 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.

FOCUS / TRACKING channel
The focus and tracking channel is the current feedback control
drive of MITSUBISHI original.The focus and tracking is the same
composition.
The relationship between the differential voltage between FOIN
and REF and the output current is shown in right Figure.
The voltage gain is 0.4 [V/V].Therefore, the current gain is
0.8[A/V] in case of the sensing resistor is 0.5 ohm.
The maximum range of output swing is limited around 7.5 volts,in
case of VM4 is above 10 volts.
