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.

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.

The relationship between the differential voltage between SPIN and REF and the torque is shown in right Figure. The voltage gain[Gvo] is 1.0 [V/V]. The current gain[Gio] is 2.0A/V (at sensing resistor : 0.5 ohm,and R1=,R2=0ohm) in forward torque directions, and the dead zone is from 0mV to 80mV (at R1=,R2=0ohm) . The coil current gain under the reverse torque is the same with in forward torque directions.And the limitation function gets on when the differential voltage of VM1(12V)~RSP is 0.5V at forward and
0.3V at reverse. Therefore current-gain-control and current-limit of this IC is determined with sensing resister value, and more detail control can be determined with setting a gain-resister outer this IC as below.

The relationship between the differential voltage between SLIN and REF and the torque is shown in right Figure. The voltage gain[Gvo] is 1.0 [V/V]. The current gain is 2.0A/V (at sensing resistor : 0.5 ohm and R1=R2) in forward torque directions, and the dead zone is from 0mV to 60mV (at R1=R2=16kohm). The coil current gain under the reverse torque is the same with in forward torque directions.And the limitation function gets on when the differential voltage of VM23(12V)~RSL is 0.5V. Therefore current-gain-control and current-limit of this IC is determined with sensing resister value.In the input part,built-in an inverted amplifier. It is possible to control more detail by setting external circuit.

The input resisters, the 10k resister to the non-inverted input and, the 2k resister to the inverted input, are built-in the operational amplifier. Therefore the composition value of the external input resisters(R1 R2) should be set 8k because of the compensation for the input offset voltage.

Recommendation of short brake mode at spindle drive
This IC has two brake mode, PWM-BRAKE-MODE and SHORT­BRAKE-MODE. In this IC recommendation, SHORT-BRAKE­MODE is superior to PWM-BRAKE-MODE to reducing the power dissipation and to avoid breaking down of this IC. (By excessive reverse torque current in braking a motor with PWM-BRAKE from high-speed-rotation with being excessive Back­EMF, this IC could be broken.)
The relationship between hall-amplifier-input and output-current-commutation/FG output at spindle

In this IC, since output tranjister is NPN-type tranjister, motor coil current (Io) is larger than sensing resistance current about 20mA (TYP.) according to base current of output tranjister. Therefore please design output current with consisting these base current.

SPINDLE MOTOR AND 4CH ACTUATOR DRIVER
The notes on designing the layout of the board
This IC has direct PWM controls for the Spindle channel and the Slide channel drive, therefore the circuits of the IC are influenced more easily by the PWM switching noise than those have linear controls. Please refer to the following notes on the ocasion of designing the layout pattern of the board on which the IC is mounted. The bad influence of the PWM noise differs in each board, therefore please consider the following notes as the reference materials for designing the board.
Note 1 It is necessary for some application in order to reduce the PWM noise that pass condensers are connected between power supply pins(VM23:4pin, VM1:22pin, VM4:38 pin, 5VCC:39pin) and GND pin, even if the power supplies of the application already have pass condensers. The closer the connection points of the condensers are to the pins, the more effective it is to reduce the noise. Please refer to the values of the condensers on the page of [An example of the values of the external parts. (The value of the condensors is only a reference value. It differs in each application because the bad influence of PWM noise relates to the layout pattern of the board.)
Note 5 The closer the GND side of the capacitor connected with OSC pin (30 pin) is to the GND pin(33pin), which is the nearest GND to the GND of the small signal circuit inside the IC, the less the bad influence of the PWM noise on the GND line comes to be. cf. [application circuit]
Note 2 The feedback point of the Spindle channel [the Slide channel] is the connected point to the VM1(22pin) [the VM23(4pin)] line from the RSP(15pin) [RSL(8pin)] pin through the sensing resistor RSP[RSL]. Therefore the closer the feedback point is to the power supply pin, the more stable the circuits are for the PWM noise. cf. [application circuit]
Note 3 The farther the large current output lines(especially PWM output lines of the Spindle CH. and the Slide CH.) which are indicated as wide lines in the Fig. [application circuit] are to the small signal input lines, the less the bad influence of the PWM noise comes to be without the cross-talk between a large current output line and a small input signal line.
Note 4
In case the PWM switching noise influences the REF input, it is necessary for some application that a condenser is connected between REF pin(25pin) and GND pin. The closer the connection points of the condensers are to the pins, the more effective it is to reduce the noise. (This is the same as note1.) cf.[application circuit], [An example of the values of the external parts]
