LS8397 Description
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 driver transistors for the two center- tapped windings in the Unipolar motor. The motor can be driven in full step mode either in normal drive (two-phase-on) or wave drive...
