AS5262 - Magnetic Position Sensor

AS5262 is a contactless Hall based magnetic position sensor created by ams OSRAM for very accurate angular measurement over a full 360°-turn. A sub-range can be programmed to achieve the best output characteristic for the application. A simple diametrical 2-pole magnet rotating on the center of the IC is required-the magnet may be placed above or below the IC. The AS5262 is a compact integrated solution which provides the absolute angle measurement with a resolution of 0.09° over a full revolution as analog ratiometric output signal. The internal 14-bit core of the AS5262 enables a new programming of the start and stop positions with a resolution of 0.02° to allow the finest system mechanical adjustments. High level of flexibility is guaranteed by the programmability through the UART interface shared with the output pin, to reduce the number of pins in the application. The angular output data can be linearized in the final production to further increase the precision of the measurement. With embedded overvoltage protection and reverse battery protection, the AS5262 can fulfill the most demanding automotive safety standards.
