ABSTRACT:
Described herein is a surface-mounted integrated current sensor for use in a printed circuit having a track along which there flows, in use, the electric current to be measured. The current sensor comprises a package having a bottom face facing, in use, the printed circuit, and on which there is set an electrically conductive bottom piece, which, in use, makes contact with the track of the printed circuit in such a way as to be traversed by the current to be measured. The current sensor moreover comprises a sensor element, for example a Hall-effect one, designed to generate a voltage proportional to the electric current that flows through the bottom piece.
