A magnetic field sensor includes first, second, and third magnetic field sensing elements having respective first, second and third maximum response axes, the first second and third maximum response axes pointing along respective first, second, and third different coordinate axes. In response to a magnetic field, the first, second, and third magnetic field sensing elements are operable to generate first second, and third magnetic field signals. Signals representative of the first, second, and third magnetic field signals are compared with thresholds to determine if the magnetic field is greater than the thresholds. A corresponding method is also provided.
