Abstract: A sensor module may include a magnet with a magnetization in a first direction, and a sensor chip including a first sensing element and a second sensing element arranged on a plane defined by the sensor chip. The first direction may be substantially parallel to the main surface of the sensor chip. The first sensing element and the second sensing element may be sensitive to an in-plane component of a magnetic field along the first direction or may be sensitive to an in-plane component of the magnetic field perpendicular to the first direction. The first sensing element and the second sensing element may be positioned beyond an edge of the magnet along the first direction such that the first sensing element and the second sensing element protrude past the edge of the magnet along the first direction.

Abstract: A magnetic sensor may include a first sensing element and a second sensing element. The first sensing element may be capable of sensing a first component of a magnetic field that is non-parallel to an axis formed by an intersection of a first plane and a second plane. The first plane may be a plane in which a tooth wheel rotates, and the second plane may include a first surface of the first sensing element and a second surface of the second sensing element. The first component of the magnetic field may be on the second plane. The second sensing element may be capable of sensing a second component of the magnetic field. The second component of the magnetic field may be on the second plane.

Abstract: A magnetic sensor module includes an axially polarized back bias magnet having a magnet body that radially extends from an inner sidewall to an outer sidewall and a bore that defines the inner sidewall. The axially polarized back bias magnet generates a radial bias magnetic in-plane field about a magnetization axis of the axially polarized back bias magnet in a sensor plane. The magnetic field has a magnetic flux density of substantially zero along the extension of the magnetization axis and along a perimeter of a zero-field closed loop located in the sensor plane. The magnetic sensor module includes a magnetic sensor including a plurality of sensor elements arranged in the sensor plane at locations where the radial bias magnetic in-plane field has the magnetic flux density of substantially zero, including at least two sensor elements being arranged on the perimeter of the zero-field closed loop.

Abstract: A current sensor includes a selector switch configured to output a first pair of differential sensor signals and a second pair of differential sensor signals if configured in a first switch state, and output a third pair of differential sensor signals and a fourth pair of differential sensor signals if configured in a second switch state; and a differential circuit coupled to the selector switch. If the selector switch is configured in the first switch state, the differential circuit is configured to generate a first output signal representative of a first difference between the first and the second pairs of differential sensor signals. If the selector switch is configured in the second switch state, the differential circuit is configured to generate a second output signal representative of a second difference between the third and the fourth pairs of differential sensor signals.
