Abstract: A magnetic switch sensor is provided having a magnetic field sensing element configured to generate a magnetic field signal in response to a magnetic field indicative of a distance or angle between the magnetic field sensing element and a target, a first circuit coupled to receive the magnetic field signal and having an output to provide a comparison signal, and a debounce circuit coupled to receive the comparison signal and having an output to provide a debounced signal. The sensor can include a second circuit having an input coupled to receive the debounced signal and an output at which is provided a toggle signal that transitions between first and second levels every other time the magnetic field signal crosses a threshold level.

Abstract: Method and apparatus for providing a motor controller/driver integrated circuit package having diagnostic processing of signal(s) from a magnetic field sensor positioned in relation to a motor. The sensor signal may have a first voltage range corresponding to a valid high state and a second voltage range corresponding to a valid low state. A diagnostic module can process the received signal from the magnetic field sensor to determine whether the received signal has a voltage level within the first or second voltage ranges. An output module may generate an output signal having a state based on the whether the received signal has a voltage level within the first or second voltage ranges.

Abstract: A magnetic field sensor includes one or more magnetic field sensing elements operable to generate a respective one or more magnetic field signals indicative of a magnetic field associated with an object, and one or more channel detector circuits coupled to receive one or more of the one or more magnetic field signals. The one or more channel detector circuits are configured to generate a respective one or more channel signals. The sensor also includes an output protocol circuit coupled to receive the one or more channel signals. The output protocol circuit is configured to generate a sensor output signal comprising distinguishable constant current levels associated with the one or more channel signals.
