Abstract
A motor home/soldout detection scheme which can sense N motors home and/or soldout, using only a two wire interface to each motor. The two wire interface can also be matrixed by row and column to further expand the interfacing ability. By channeling the home signal from the control board through the soldout switch the detection of soldout can be assured.
