1. A Hall effect sensor adapted driver circuit system, the system comprising:
a transformer;
a Hall effect sensor including an input port operably coupled to receive a drive signal and an output port operably coupled to provide a regulated signal to an input port of the transformer, wherein, when enabled, the Hall effect sensor configured to detect electromagnetic coupling of the transformer; and
a drive-sense circuit (DSC) operably coupled to the Hall effect sensor via a single line, wherein, when enabled, the DSC operably coupled and configured to:
provide the drive signal via the single line that operably couples the DSC to the Hall effect sensor and simultaneously to sense the drive signal via the single line;
detect an effect on the drive signal based on exposure of the Hall effect sensor to the electromagnetic coupling of the transformer; and
generate a digital signal representative of the effect on the drive signal.
