Abstract
A current sensor comprises a flat housing made of plastic having an underside and an upper side and electrical connections, a current conductor through which the current to be measured flows, and a semiconductor chip having two magnetic field sensors, wherein the component of the magnetic field detected by the two magnetic field sensors points in opposite directions at the locations of the two magnetic field sensors. The semiconductor chip is connected as flipchip to the electrical connections. The current conductor extends from one side wall to the opposite side wall of the housing, is embedded flat in the underside of the housing and is therefore exposed on the underside of the housing. The opposing surfaces of the semiconductor chip and the current conductor are separated by an electrical insulation layer.
