Patent ID: 8412432

Claim:
A protective circuit arranged on a printed circuit board comprising: at least one supply voltage track on the printed circuit board, at least one semiconductor switch with a plurality of terminals on the printed circuit board, an at least one control component with at least one terminal on the printed circuit board that is electrically connected to a first terminal of the semiconductor switch, a first conductor loop connected to an electronic evaluation unit, the first conductor loop arranged on the printed circuit board so that it surrounds an electrically conducting connection between the supply voltage track and the control component, and a second conductor loop, which is arranged on the printed circuit board so that it screens the electrically conducting connection between the first terminal of the control component and the first terminal of the semiconductor switch from the semiconductor switch, and at least from those regions of the control component which are also connected to the supply voltage track, the second conductor loop also completely surrounding the first terminal of the control component and the first terminal of the of the semiconductor switch.
