Melexis MLX90422GVD-ADD-030-RE

MLX90422 is a monolithic magnetic position sensor IC. It consists of a Triaxis® Hall magnetic front-end, an analog-to-digital signal conditioner, a DSP for advanced signal processing, and a programmable output stage driver. The MLX90422 is sensitive to all three components of the magnetic flux density applied to the IC (i.e., Bx, By, and Bz). Programming the sensor determines which axes are used to calculate rotational or linear position. This enables the MLX90422, combined with the appropriate magnetic design, to calculate the absolute position of any moving magnet (e.g., rotational position from 0 to 360 degrees). It facilitates the design of contactless position sensors, which are frequently required in automotive and industrial applications. The MLX90422 provides SENT frames encoded according to the single safe sensor A.3 (H.4) or dual throttle position sensor A.1 (H.1) format. The circuit can provide enhanced serial messages, including error codes and user-defined values.
