Melexis MLX90384
The MLX90384 is a four-component set (a,b,c,d), providing a flexible solution for your high-accuracy magnetic encoder needs. The ICs are both configured to be sensitive to a first magnetic flux density component parallel with the chip plane and to a second component perpendicular to the chip. The MLX90384 sensor chip measures the axial and tangential magnetic components of both tracks and transmits this information to a microcontroller which in turn generates the accurate angular position as well as the counted turn out of this information.FEATURES
