Abstract:
Systems and methods described herein provide a current sensor based on magnetic field detection having multiple sensor arrangements with multiple, different sensitivity ranges. The outputs of the multiple sensor arrangements can be combined to generate a single output signal. The current sensor can include two or more sensor arrangements, each having one or more magnetic field sensing elements, and configured to sense a magnetic field in different first measurement ranges corresponding to different ranges of currents through the conductor and further configured to generate different magnetic field signals indicative of the sensed magnetic field in the respective measurement range. The current sensor can include a circuit configured to generate an output signal indicative of a combination of the different magnetic field signals that corresponds to the current through the conductor.
