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.

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

THERMAL CHARACTERISTICS

The guranteed max. temperature is Tj max. which is shown in "9. ABSOLUTE MAXIMUM RATING". The TSD function is a thermal protection in case

the temperature of the devices goes up above Tjmax because of wrong use.
And these TSD temperature are the target temperatures for circuit design, not the guranteed temperatures.
(The TSD function of all the devices is not checked by a test in high temperature.)

unction start temperature doesn't show the guaranteed max. temperature of the devices.

MU1
SELECT2
SELECT1

This IC has MUTE terminal (MU1).
It is possible to control ON / OFF of the channel by external logic
inputs.
In case of SELECT1, the bias of all circuit becomes OFF.
Therefore, this mode is available in order to reduce the power
dissipation when the waiting mode.
In case of SELECT2,the bias of all channel becomes ON.

L/Open

This IC has BRS terminal (BRS).
It is possible for a braking timiming of Spindle drive to select which the
short brake or the reverse brake by BRS.
It shuould select the short brake in case of high speed system and
please change to the reverse brake when the rotation speed becomes
enough low. It is available when the SPIN voltage is low than the
reference voltage.

● Loading channel

r

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 fo
this channel to have the stop function.
