Abstract

The invention relates to a semiconductor switch and to a method for determining a current in the power path of a semiconductor switch. For this purpose, a semiconductor switch, according to the invention, has a plurality of sense connections, wherein each of said sense connections provides an individual output signal that is proportional to the current in the power path of the semiconductor switch. The evaluation of the current in the power path can be optimized by the appropriate selection of one of the plurality of sense connections in accordance with the current in the power path of the semiconductor switch.
