Abstract
A current sensor comprises a housing of plastic, a current conductor with integrally shaped first and second electrical terminals, through which a current to be measured is supplied and discharged, third electrical terminals, and a semiconductor chip having at least one magnetic field sensor, which is sensitive to a component of the magnetic field generated by the current flowing through the current conductor running perpendicularly to the surface of the semiconductor chip. The first and second electrical terminals are arranged at a first side of the housing, the third electrical terminals are arranged at a side of the housing opposite to the first side. The semiconductor chip is mounted as flip chip. The semiconductor chip comprises first bumps, which make electrical connections to the third terminals, and second bumps located above the current conductor and electrically separated from the semiconductor chip by an isolation layer.
