Abstract
A current sensor for sensing a current through a conductor includes a magnetic field sensing element configured to generate a magnetic field signal indicative of a magnetic field associated with the current through the conductor, a first processing path responsive to the magnetic field signal and configured to generate a first current sensor output signal, a resistive element coupled to the conductor, a second processing path coupled across the resistive element and configured to measure a voltage across the resistive element and generate a second current sensor output signal, and a shared processor configured to calibrate the first processing path and second processing path. The shared processor can be configured to generate one or more of a sensitivity calibration signal, a temperature calibration signal, an offset calibration signal, or a lifetime drift calibration signal.
