Abstract: The present disclosure provides a method of providing quadrant information to a magnetic sensing device comprising a magnetic angle sensor, and in particular, a magnetic angle sensor configured to provide 180° absolute angle measurements, such as a 180° anisotropic magnetoresistive (AMR) angle sensor, such that the magnetic sensing device outputs an analog signal encoded with 360° information. In this respect, magnetic sensing device is provided with a magnetic angle sensor and a quadrant detector, which may be provided on the same substrate or two separate substrates, wherein the signal from the quadrant detector is encoded into the analog sine and cosine voltage outputs from the magnetic angle sensor such that the two analog outputs provide 360° angle information.

Abstract: Automatic power saving for decreasing power demand during a power interruption while maintaining the appearance of full operation of a signal processor including predefined power consuming circuits, a communications interface, and a state machine includes sensing when a power supply interruption has occurred, providing a clock signal, halting the clock signal to the predefined power consuming circuits during a power interruption; and continuing to provide a clock signal to a communications interface regardless of a sensed interruption for maintaining the appearance of normal operations during the sensed interruption.
