    Abstract: A device for detecting an electrical overcurrent event includes a current sensor configured to generate a first sense signal representative of an absolute current value of an electrical current through an electrical conductor. The device further includes a sense unit configured to generate a second sense signal representative of a temporal change of the electrical current. The device further includes an adjustment unit configured to adjust a previously set first threshold value for the absolute current value based on the second sense signal. The device further includes a detection unit configured to detect an overcurrent event in the electrical conductor based on a comparison between the first sense signal and the adjusted first threshold value.

    Abstract: A sensor device includes an electrically conductive carrier and a magnetic field sensor mounted on the electrically conductive carrier. The magnetic field sensor includes a first pair of first sensing elements configured to provide a first differential signal representative of a magnetic field generated by an electrical current through an electrical conductor and by eddy currents generated in the electrically conductive carrier. The magnetic field sensor further includes a second pair of second sensing elements configured to provide a second differential signal representative of a magnetic field generated by the eddy currents and independent of a magnetic field generated by the electrical current through the electrical conductor. The sensor device further includes a unit configured to provide an output signal based on a difference or a sum including the first differential signal and the second differential signal.
