Abstract:
A controller comprising a driver interface referenced to a first reference potential, a drive circuit referenced to a second reference potential, and an inductive coupling. The driver interface comprises a first receiver configured to compare a portion of signals having a first polarity on the first terminal of the inductive coupling with a first threshold, and a second receiver configured to compare a portion of signals having a second polarity on the second terminal of the inductive coupling with a third threshold. The drive circuit comprises a first transmitter configured to drive current in a first direction in the second winding to transmit first signals, and a second transmitter configured to drive current in a second direction in the second winding to transmit second signals, the second direction opposite the first direction.
