Supplementary Explanation
1.
V
CD
supply
The V
CD
line is the power supply for the driver control blocks of channels 1 to 4. The VCD line can be supplied from the
DSP or ASP step-up circuit by using a coil with center tap (as shown in the Block Diagram).
However, because the allowable operating range for V
CD
is 3.6 V to 9.0 V, it is recommended that in order to reduce power
dissipation, the voltage should be set to the lower range. (Even if this power supply does not affect the control performance
such as the transfer gain.)
Sled step drive
Stepping control in this IC for the sled actuator is as described below. Normal V-type control is selected if the SLMODE pin
is set high, but by setting this pin low step drive mode with low power dissipation can be selected. (This only affects channel
4.)
The step drive starting level is input from the SLREF pin (must be higher than ASPREF), and the positive side step start is
determined by comparing the input voltage with IN4. For the negative side, the step start is determined automatically by
setting the differential voltage between the SLREF and the ASPREF on the opposite side, and then comparing that voltage to
IN4. In other words, the control characteristics become as defined by the solid line in the diagram below. (The rise on the
positive and negative steps has no hysteresis.)

Voltage between outputs
SLREF (greater than ASPREF)
If this voltage is set, the negative side step
start is determined automatically by setting the
differential voltage betwwen SLREF and
ASPREF on the opposite side as well.
