A semiconductor switch arrangement

摘要

A semiconductor switch arrangement (300) comprising a bipolar transistor (302) and a semiconductor power switch (301) having an input node (306), an output node (304) and a control node (305) for allowing a current path to be formed between the input node (306) and the output node (307), wherein the bipolar transistor (302) is coupled between the input node (306) and the control node (305) to allow a current to flow from the input node (306) to the control node (305) upon a predetermined voltage being exceeded at the input node (306) to allow the control node (305) to cause a current to flow from the input node (306) to the output node (307).
