Protective Arrangement for the Protection of Safety-Relevant Electronic Circuits from Malfunctions
First Claim
1. 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 at least one terminal on the printed circuit board, andat least one control component with at least one terminal on the printed circuit board, a first terminal of the control component and a first terminal of the semiconductor switch being connected electrically,a first conductor loop, which is arranged on the printed circuit board so that it surrounds an electrically conducting connection between the supply voltage track and the semiconductor switch and the control component, anda 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.

Abstract
A protective circuit arranged on a printed circuit board has two conductor loops. At least one supply voltage track, at least one semiconductor switch with at least one terminal and at least one control component with at least one terminal are arranged on the printed circuit board. A first terminal of the control component and a first terminal of the semiconductor switch are connected electrically. A first conductor loop of the protective circuit is arranged on the printed circuit board so that it surrounds an electrically conducting connection between the supply voltage track and the semiconductor switch and/or the control component, and a second conductor loop is arranged on the printed circuit board so that it surrounds the electrically conducting connection between the first terminal of the control component and the first terminal of the semiconductor switch, and thereby screens the same from the semiconductor switch and at least from those regions of the control component that are also connected to the supply voltage track.
