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.

s package is
improving the board on which the IC is
mounted enables a large power dissipation
without a heat sink.
For example, using an 1 layer glass epoxy
resin board, the IC's power dissipation is

2.6W at least. And it comes to 3.6W by
using an improved 2 layer board.
The information of the N, P, O type board is

This IC has two MUTE terminal (MU1 and MU2).
It is possible to control ON / OFF of each channel by external logic
inputs.
It has four kinds of function for select.In case of SELECT1, the bias
of all circuit becomes OFF.
Therefore, this mode is available in order to reduce the powe
dissipation when the waiting mode.
In case of SELECT2,it is possible to select the PWM reverse
braking to take the brake of Spindle motor.

● 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.
The output becomes high impedance in case of both input voltage
becomes under 0.5 volts. It is possible for the input terminal to
operate from 0 volts.The following table and diagram show an
application in case of two MCU port and one MCU port for the
loading motor.In case of one MCU port, if use three state port, it is
possible for this channel to have the stop function.
