AS5147U-HTSM

AS5147U-HTSM is a 14-bit dual-die n-axis magnetic rotary position sensor with up to 14-bit binary incremental pulse count. It is a high-resolution redundant rotary position sensor for fast absolute angle measurement over a full 360-degree range. This position sensor is equipped with a revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency at higher rotational speed. For increased signal quality at lower rotational speed, the dynamic filter system (DFS™) reduces transition noise. The robust design of the device suppresses the influence of any homogenous external stray magnetic field. The AS5x47U has been designed to support BLDC motor communication for the most challenging and safety-critical automotive applications (AEC-Q100 grade 0 automotive qualified – ISO26262 assessment) such as electric power steering (EPS), transmission (gearbox, actuator), brake (actuator) and starter/alternator.
