AS5172E/AS5172F High-Resolution On-Axis Magnetic Angular Position Sensor with PSI5 Output The AS5172E/F is a magnetic position sensor with a high General Description 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. The absolute angle measurement provides an instant indication of the magnets angular position. The AS5172E/F 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. Programmability over the VDD pin reduces the number of pins on the application connector. The AS5172E/F is available in a TSSOP14 package and in a SIP package. The SIP package (System in Package) has integrated the AS5172E/F sensor die together with the decoupling capacitors necessary to pass system level ESD and EMC requirements. No additional components and PCB on the sensor side are needed. The product is defined as SEooC (Safety Element out of Context) according ISO26262. The product is fully system level EMC and ESD tested according OEM standards.
