Speed [rpm] Overvoltage Protection: Yes Redundant Supply Voltage [V]: 4.0 to 12.0 Temperature Range [°C]AS5172A: -40 to +125 / AS5172B: -40 to +150 Package: AS5172A: SiP (system in package) / AS5172B: TSSOP Automotive Qualified: Yes General Description The AS5172 is a magnetic position sensor with a high-resolution 12-bit PSI5 output according PSI5 specification Version 1.3 and 2.1. Based on a Hall sensor technology, this device measures the orthogonal component of the flux density (Bz) over a full-turn rotation and compensates for external stray magnetic fields with a robust architecture based on a 14-bit sensor array and analog front-end (AFE). A sub-range can programmed to achieve the best resolution for the application. To measure the angle, only a simple two-pole magnet rotating over the center of the package is required. The magnet may be placed above or below the device.
