ABSTRACT:
Switching circuit that receives a supply voltage, a reference voltage, a line adapted to carry a negative voltage and a control signal, the switching circuit capable of providing at an output a voltage alternatively equal to the reference voltage or to the voltage of the line in response to the control signal. The circuit includes a first MOSFET with a first electrode operationally connected to the line, a second electrode operationally connected to the output, and a control electrode, a second MOSFET with a first electrode operationally connected to the reference voltage, a second electrode operationally connected to the output, and a control electrode, and driving circuitry adapted to bring the control electrodes of the first and second MOSFETs respectively to the supply voltage and to the voltage of the line or, alternatively, to the voltage of the line and to the supply voltage, in response to the control signal.
