  • Magnetic sensor, a magnetic detection apparatus, and a magnetic detection method
    Patent number: 10677858
    Abstract: To downsize a magnetic sensor by reducing the number of terminals of the magnetic sensor. A magnetic sensor to detect a magnetic field is provided, including: a drive terminal; a first output terminal; a second output terminal; and a magnetic sensing unit in which a first conduction path through which a driving current flows between the drive terminal and the first output terminal and a second conduction path through which a driving current flows between the drive terminal and the second output terminal are formed integrally. The magnetic sensing unit may have a first extending unit extending to the first output terminal and a second extending unit extending to the second output terminal.
    Type: Grant

  • Magnetic sensor
    Patent number: 9964601
    Abstract: The magnetic sensor includes a magnetic flux concentrator member having a length in a direction of a second axis, a first magnetic detector arranged on a negative side of a first axis from the magnetic flux concentrator member and on a positive side of the second axis from a midpoint of the magnetic flux concentrator member in a length direction, a second magnetic detector arranged on a positive side of the first axis from the magnetic flux concentrator member and on the positive side of the second axis from the midpoint of the magnetic flux concentrator member in the length direction, and a third magnetic detector arranged on the negative side of the first axis from the magnetic flux concentrator member and on a negative side of the second axis from the midpoint of the magnetic flux concentrator member in the length direction.
