AS5162-HSOM

AS5162-HSOM is a 12bit contactless magnetic angle position sensor for accurate angular measurement over a full turn of 360°. A sub range can be programmed to achieve the best resolution for the application. It is a system-on-chip, combining integrated hall elements, analog front end, digital signal processing and best in class automotive protection features in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.022° = 16384 positions per revolution. According to this resolution the adjustment of the application specific mechanical positions are possible. It is ideal for automotive applications like throttle and valve position sensing, gearbox position sensor, tumble flap, chassis height level, pedal position sensing, contactless potentiometers.
