LS8397 controller equivalent, stepper motor controller.
* Controls Bipolar and Unipolar Motors
* L297 operation with added functions:
* Selectable torque ripple compensated phase drive
* Selectable automated s.
The LS8397 Stepper Motor Controller generates four phase drive signal outputs for controlling two phase Bipolar and four phase Unipolar motors. The outputs are used to drive two H-bridges for the two motor windings in the Bipolar motor or the four d.
