Abstract

Die vorliegende Erfindung betrifft eine Treiberschaltung zum Treiben eines spannungsempfindlichen Verbrauchers (8,31) von einem entfernt liegenden Steuergerät aus. Um kostengünstig zu sein und gleichzeitig Statussignale auswerten zu können wird vorgeschlagen, die Treiberschaltung selbst zur Aufrechterhaltung eines sicheren Betriebszustands des Verbrauchers vorzusehen. Dies wird realisiert durch eine steuerbare Stromquelle (T1), ein die Stromquelle ansteuerndes Regelelement (T2, T3) mit einem ersten Eingang (18) von einer vorgegebenen Referenzspannung (VCC) und einen zweiten Eingang (19) zur Zuführung der Regelspannung für den Verbraucher (8,31).
