A4980
Automotive, Programmable Stepper Driver
reference value. Although the current in Q3 and Q4 for phase A is
effectively negative, the negation is provided by controlling the
direction of the current. The current control scheme still operates
using positive values.
As shown below, the table of values can be extended to include
Q3 and Q4 with the current direction indicated in the last column.
Note that the same value is now applied to four locations in the
full 360-degree electrical cycle.
Shown outlined above, steps 4, 28, 36, and 60 all contain the
value 23.
The other phase, phase B, uses the same values as phase A but
shifted back by 16 Step Angle Numbers. The full distribution of
the value entered in step 4 of phase A is highlighted in figure 12
(and shown in table 7). This single value is used in a total of eight
locations. The same distribution of values applies to all the values
in steps 1 to 15. These values are defined in the A4980 as PT(0)
to PT(14), respectively.

There are two exceptions to this data distribution principal. These
are the zero value and the maximum value:

? The values in phase A steps 0 and 32 and phase B steps 16 and
48 are always set to zero and cannot be programmed.
? The maximum value, PT(15), is distributed to only two Step
Angle Numbers in each phase. These are the points in the cycle
where the peak current is required, namely phase A steps 16 and
48 and phase B steps 0 and 32.
