Melexis MLX90377GVE-ADB-510-RE

MLX90377 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 an output stage driver. The MLX90377 is sensitive to all three components of the magnetic flux density applied to the IC (i.e., Bx, By, and Bz). This enables the MLX90377, combined with an appropriate magnetic circuit, to decode the absolute position of any moving magnet (e.g., rotational position from 0 to 360 degrees or linear displacement). It enables the design of contactless position sensors, which are frequently required in automotive and industrial applications. The MLX90377 offers 4 output modes. First, the IC supports (fast) SENT and SPC frames encoded in a safety sensor format. The output provides enhanced serial messages containing error codes and user-defined values. Through programming, the MLX90377 can also be configured to output a PWM signal. Finally, analog ratiometric output is also supported.
