Abstract
A switching device may include an input terminal, an output terminal, a primary switching transistor coupled between the input terminal and the output terminal, logic circuitry configured to receive a control signal to selectively activate the switching device, a first cascode arrangement coupled between the logic circuitry and a first reference voltage supply, and a second cascode arrangement coupled between the input terminal and the primary switching transistor. The first cascode arrangement may include cascode transistors having gate terminals coupled to a first voltage divider coupled between the first reference voltage supply and a second reference voltage supply that is coupled to the logic circuitry. The second cascode arrangement may include a first cascode transistor coupled to a fixed voltage at the first voltage divider and second and third cascode transistors coupled to variable cascode bias voltages at a second voltage divider coupled to a variable voltage input.
