A magnetic field sensor that detects an angle of a target includes a first channel having first and second magnetic field sensing elements that are orthogonal with respect to each other and produce first and second magnetic field signals, and a second channel having third and fourth magnetic field sensing elements that are orthogonal with respect to each other and produce third and fourth magnetic field signals. The third sensing element is positioned at an angle (e.g., 45-degrees) with respect to the first sensing element. The magnetic field sensor includes a low power mode circuit that uses comparators to compare the first, second, third, and fourth magnetic field signals to a first, second, third, and fourth threshold, respectively. A processor is configured to use an output of the low power mode circuit to determine the angle of the target.
