QuarterStep Operation
It ispreferableto realize the quarterstep operation
at full power otherwise the steps will be of very ir-
regular size.

Motor Selection
As the PBL3717Aprovides constant current drive,
withaswitchingoperation,caremustbetakentose-
lect stepper motors with low hysteresis losses to
preventmotor over heat.
L -CFilter
To reduceEMI and choppinglossesin themotora
low pass L -C filter can be inserted across the out-
putsofthePBL3717Aasshownonthefollowingpic-
