Abstract:
A circuit arrangement for overload protection of a first control element comprising:a voltage source; a load; a first control element having a first control path selectively connecting the voltage source to the load, at least one control input for selectively controlling the first control path, and at least one output terminal connected to the load and at least one input terminal connected to the voltage source, wherein the at least one output terminal connected to the load and the at least one input terminal connected to the voltage source respectively comprise a first control path output and a first control path input; a protective circuit arranged electrically parallel to the first control path of the first control element, wherein the protective circuit is configured to monitor voltage across the first control path of the first control element and, drive the control input of the first control element when a short in the load occurs such that the load is separated from the voltage source.
