Determining the output current
Fig. 1 shows the waveform of the output current (motor coil
current). The method of determining the peak value (lo) of
the output current based on this waveform is shown below.

(1) Normal rotation mode
lo is determined as follows when current flows at the
maximum level during motor rotation. See Fig. 2, 3 and

(2) Power down mode
The circuits in Fig. 5, 6 and 7 (rx and Tr) are added in
order to decrease the coil current. lo is then determined
as follows.
