ams AS5172_EVM_PB Evaluation board

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 be 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. The absolute angle measurement provides an instant indication of the magnet’s angular position. The AS5172 operates up to a voltage of 16.5V and is protected against overvoltage up to +20V. In addition, the supply pins are protected against reverse polarity up to – 18V.
