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

q Loading channel
The loading channel is the circuit of BTL voltage drive. This circuit
has the referential input. Output swing is determined with ∆Vin X 8.
Also,it is possible for this channel to use for the slide motor , the
focus coil and the tracking coil.
The input terminal is high impedance. It is possible to do variable a
gain by external resistor.
In case of one MCU port, if use three state port, it is possible for
this channel to have the stop function.
