Abstract
In one embodiment, a control system includes a first voltage domain circuit. The first voltage domain circuit includes circuitry for operating in a first voltage domain. The control system includes a second voltage domain circuit. The second voltage domain circuit includes circuitry for operating in a second voltage domain. The second voltage domain circuit includes a driver circuit. The driver circuit for providing a control terminal driving signal to make conductive a power switch. The second voltage domain circuit includes a replication circuit, the replication circuit having an output to provide a replicated signal of the control terminal driving signal. The control system includes a galvanic isolation barrier signal path between the first voltage domain circuit and the second voltage domain circuit. The replicated signal is provided by the second voltage domain circuit to the first voltage domain circuit via the galvanic isolation barrier signal path.
