[FEATURES]

[APPLICATION]

CD-ROM, DVD, DVD-ROM, DVD-RAM,Optical disc related system,etc

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 driven 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 three voltage

supply can be set separately.

This IC's package is POWER-SSOP,

so improving the board on which the

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 20A/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 0.5Vat forward and 0.3V at reverse
in case of SELECT6, SELECT7,SELECT8 the differential voltage of VM1
(12V) RSP is 0.3Vat forward. Therefore ,this mode is available in order
to reduce a temperature under acceleration.
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 spindle and the slide channel is controlled by the direct PWM control.
Analog input voltage control the driving current which is in proportion to input voltage.
This control is direct PWM control type of motor current chopper.
Also,built-in the current limit circuit. This IC controls the motor current directly.
direct PWM operation as follows;
1) The current which flows on a motor is detected, and current is supplied
from a power supply until it reaches the predetermined instruction value
to which the current is proportional to input voltage.
2) When current reaches an instruction value, an output transistor is changed and
the period coil inertia energy to a career cycle is made to regeneration using an internal path.
3) After repeat 1) and 2).
Therefore, the IC constantly surveillance and control the current value itself use sensor resistor.
Moreover, these ICs built-in current limit circuit so that protect to large current.
Thus, if input excessive control voltage, the current don't flow that settle limit current.

Recommendation of SHORT BRAKE MODE at Spindle DRIVE

This IC has two brake mode, PWM-BRAKE-MODE and SHORT-BRAKE-MODE. IN this IC recommendation,
SHORT-BRAKE-MODE 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 Back-EMF, this IC could be broken.)

FG function at Spindle DRIVE

The FG terminal outputs the square pulse signal synchronizing with the Hall inputs [Hu+,Hu-,
Hv+, Hv-,Hw+,Hw-] timing.And, the FG terminal is open-collector output.
(cf.FG timing chart on the previous page)

Phase delay circuit at Slide

Phase delay circuit is built in the IC to detect an output spike current, when the Motor current
direction is switching.
IN switching the Motor current direction, Phase delay circuit switch-off all output transistor of H-
bridge for 3usec.

Output current setting at Slide

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

[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 occasion of designing the layout pattern of the board on which the IC is mounted.

note1

I t 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, 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 condensers 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.)

note2

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]

note3

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.

[The Notes on designing the layout of the board]

note5

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]

note4

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.)
