Setting Output Current
The motor output current waveform is shown to the right.
Output current I
OH
can be set by the user by adjusting the
voltage of pin 9 (11).
The computation equation is indicated below.

K: 1.1 to 1.2 (correction for actual measurement)
Power down can be accomplished by reducing the synthetic
impedance by connecting a resistance in parallel to R

The motor output current variation range can be set for the
range of:
I
OH
= 0.2 A to 1.7 A
but when set to I
OH
= 0.2 A or lower note that the HIC GND pattern will be one-point earth with respect to the power
supply. If earth is poor, there may be no motor current when I
OH
= 0.2 A. We recommend a motor inductance usage
range of L = 1 mH to 10 mH.
