AS5173 Magnetic Position Sensor

Infineon Technologies AS5173 Magnetic Position Sensor comes with a high-resolution 12-bit or 14-bit PSI5 output, in accordance with the PSI5 specification, Versions 1.3 and 2.3. Based on Hall sensor technology, this device measures the flux density Bz orthogonal to the die surface, over a full-turn rotation. The Infineon Technologies AS5173 compensates for external stray magnetic fields with a robust architecture that uses a 14-bit sensor array and an analog front-end (AFE). A sub-range smaller than 360° can be programmed to achieve excellent resolution for the application. A two-pole magnet rotating over the center of the package is required to measure the angle.
