Abstract

A bi-directional switch circuit includes first and second transistors having their control electrodes coupled at a first common node and the current paths coupled at a second common node in an anti-series arrangement. First and second electrical paths coupled between the first common node and the first and second transistors, respectively, include first and second switches switchable between a conductive state and a non-conductive state. A third electrical path between the first and second common nodes includes a third switch switchable between a conductive state and a non-conductive state. The third switch is coupled with the first and second switches by a logical network configured to switch the third switch to the conductive state with the first and second switches switched to the non-conductive state, and to the non-conductive state with either one of the first and second switches switched to the conductive state.
