  • Publication number: 20240060796
    Abstract: A magnetic sensor package comprising a magnetic multi-turn sensor die and a magnetic single turn sensor die, in which both sensor dies are packaged on the same lead frame. A method of manufacturing the magnetic sensor package is also provided. A magnetic sensor system comprising a rotating magnet and the magnetic sensor package, where the sensor package is arranged so that both sensor dies sit within a homogenous magnetic field, thereby ensuring that the output signal of each sensor is not corrupted by any stray fields.
    Type: Application

  • Publication number: 20220326049
    Abstract: The present disclosure provides magnetic sensor system that includes a magnet mounted on the end of a rotating shaft, a magnetic sensing device comprising a magnetic multi-turn sensor, and a mechanism for initializing the magnetic multi-turn sensor into a known state ready for use. Whilst the magnetic sensing device is being used to monitor the rotation of the shaft, the magnet is located in a starting position a first distance from the magnet sensing device such that the magnet field strength experienced by the magnet sensing device is within the operating window of the magnet multi-turn sensor, the operating window being defined by a minimum magnetic flux density, Bmin, and a maximum magnetic flux density, Bmax. The mechanism comprises a means for moving the magnet and the shaft in an axial direction towards the magnet sensing device such that the magnetic field experienced by the magnet sensing device exceeds the upper limit, Bmax, of the operating window.

  • Patent number: 10859406
    Abstract: Aspects of the present disclosure relate to correcting for a phase shift between signals associated with an angle sensor and a multi-turn sensor that includes magnetoresistive elements. A processing circuit can determine a phase shift correction and generate position information based on at least the phase shift correction and a signal associated with the multi-turn sensor.
