Overview
The sensor package tip is placed inside a dipole bias magnet. The TMR sensing elements sense the rotation of this dipole magnet and acquire the rotating magnetic field signals. Digital signal processing algorithms and high-speed circuitry compute the rotation angle from these signals. The sensor outputs 16-bit absolute position signal through a fast serial communication, with rotational speeds up to 30,000 RPM. The sensor has dynamic offset and gain calibration to compensate for misalignment between the sensor and the dipole bias magnet.
