Abstract
Switching circuitry includes first and second transistors in series between two terminals and including a common control node with a capacitance between the common control node and an intermediate point. A control circuit includes first and second circuits configured to charge and discharge the capacitance as a function of first and second control signals. The control circuit includes a third circuit having a plurality of diodes and a switch that operates when the voltage at the capacitance is greater than a threshold two diodes in cascade between the intermediate point and the common control node to enable current flow from the intermediate point to the common control node. When the voltage at the capacitance is smaller than the given threshold two diodes are connected in series between the common control node and the intermediate point to enable current flow from the common control node to the intermediate point.
