PROTECTIVE ARRANGEMENT FOR THE PROTECTION OF SAFETY-RELEVANT ELECTRONIC CIRCUITS FROM MALFUNCTION

摘要

A protective circuit being disposed on a printed circuit board has two conductor loops. At least one supply voltage conductor path, at least one semiconductor switch having at least one terminal, and at least one activation module comprising at least one terminal, are disposed on the printed circuit board. A first terminal of the activation module and a first terminal of the semiconductor switch are connected in an electrically conducting manner. A first conductor loop of the protective circuit is disposed on the printed circuit board such that the said first conductor loop encompasses an electrically conducting connection between the supply voltage conductor path and the semiconductor switch or the activation module, and a second conductor loop is disposed on the printed circuit board such that the said second conductor loop encompasses the electrically conducting connection between the first terminal of the activation module and the first terminal of the semiconductor switch, thus shielding the same from the semiconductor switch, and at least from the regions of the activation module that are also connected to the supply voltage conductor path.
