Abstract
A high current end power stage comprises at least four power transistors, two electrical supply lines and a safety fuse. The at least four power transistors have each a diode which is blocked during normal operation of the respective power transistor. The two electrical supply lines couple the at least four power transistors with a supply potential and a reference potential such that two of the at least four power transistors are connected electrically between the supply potential and the reference potential. The safety fuse is connected in series to the at least four power transistors in at least one of the two electrical supply lines. The at least one safety fuse can be triggered by a current which flows through the diode of the at least four power transistors, said diode being then arranged in the direction of conduction, when the supply potential and reference potential are exchanged.
