An integrated circuit is described having a substrate, a power transistor in a first region of the subtracted, and a plurality of barrier regions of the substrate around the first region. Each barrier region includes a barrier transistor and at least one substrate connection connecting the barrier transistor to at least one floating region of the substrate adjacent the barrier region. During operation of the integrated circuit, the floating regions and the barrier transistors operate to inhibit operation of parasitic devices associated with the power transistor
