AS5161 and AS5262
Magnetic Position Sensors


The AS5161 and AS5262 are immune to stray magnetic fields, enable functional safety, and have precise angle measurements


ams' AS5161 and AS5262 Magnetic Position SensorsThe AS5161 and AS5262 are contactless, Hall-based magnetic position sensors created by ams for accurate angular measurement over a full 360° turn. A sub-range can achieve the best output characteristics for the application through programming. A simple diametrical 2-pole magnet rotating on the center of the IC is required. The magnet works either above or below the IC. The AS5161 is a compact, integrated solution that provides the absolute angle measurement with a resolution of 0.09° over a full revolution as PWM output signal. The AS5262 provides the absolute angle measurement with a resolution of 0.09° over a full revolution as an analog ratiometric output signal. The internal 14-bit core of the AS5161 and AS5262 enables a new programming of the start and stop positions with a resolution of 0.02°. This allows the finest system mechanical adjustments. The programmability guarantees a high level of flexibility through the UART interface shared with the output pin. This reduces 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 AS5161 and AS5262 can fulfill the most demanding automotive safety standards.
