PBL3717A
Quarter Step Operation
It is preferable to realize the quarter step operation
at full power otherwise the steps will be of very ir-
regular size.
The extra quarter steps are added to the half steps
sequence by putting one coil on half current accord-
ing to the sequence.
Motor Selection
As the PBL3717A provides constant current drive,
with a switching operation, care must be taken to se-
lect stepper motors with low hysteresis losses to
prevent motor over heat.

L -C Filter
To reduce EMI and chopping losses in the motor a
low pass L -C filter can be inserted across the out-
puts of the PBL3717A as shown on the following pic-
ture.
