Abstract:
1. A driving circuit for a switch that includes first and second transistors coupled in series to each other and to relative intrinsic diodes in antiseries and driven by the driving circuit, wherein the driving circuit comprises: at least one first and one second output terminal coupled to the switch and adapted to supply the switch with a first control signal for driving said switch in a first working state and a second control signal for driving said switch in a second working state, and in that it comprises at least one latch circuit coupled between respective common gate and source terminals of said first and second transistors and adapted to supply said common gate terminal with said first and second control signals, respectively, according to said working state for the turn off, and respectively the turn on, of said first and second transistors; and at least one first and one second generator of said control signals, connected, by means of respective first and second switches driven by respective control signals, to said first and second output terminals of said driving circuit.
