Rev. 1.0.1
February. 2000.

3. Voltage Control
Even though FAN8486D command uses Ic to control the magnitude of I
O
, it can also use voltage. FAN8486D mainly uses
voltage control and has option to use current control.
Figure 4.
Figure 4 shows the principle of the voltage control.
The V
CTL
is the motor speed control voltage, and the I
CTL
is converted to current through the V / I converter.
Figure 5 shows the graph of V
CTL
vs. I
O
.
