Anyone have a recommendation for the output drivers for driving a stepper motor using vector control.
I've looked at a number of the parts and they either have an indexer in them that you can't get around, or they default back to simple bridge driving.
I'd like current control built in. Like an 8711, but something that I can set the outputs to what I want. It would also be nice if the current sense amplitude was pinned out so that I could digitize it and look at back emf.
Thanks,
Gary
