MLX90374 Position Sensor

Melexis' MLX90374 monolithic magnetic position processor IC enables the design of contactless position sensors in automotive and industrial applications

Image of Melexis' MLX90374 position sensor Melexis' Triaxis™ series position sensor MLX90374 features two output drivers, stray-field robustness for high operating voltage and temperature operation.

The MLX90374 is a monolithic magnetic position processor IC. It consists of a Triaxis Hall magnetic front end, an analog-to-digital signal conditioner, a DSP for advanced signal processing and a dual output stage driver.

The MLX90374 is sensitive to three magnetic flux density components (ie Bx, By and Bz) applied to the IC. This allows the MLX90374 with the correct magnetic circuit to decode the absolute position of any moving magnet (eg rotational position or linear displacement from 0 to 360°). It enables the design of non-contact position sensors often required in automotive and industrial applications.

The MLX90374 offers dual PWM outputs or a combination of SENT and programmable switching functions. In dual PWM output mode, the circuit offers a wide range of configurations, from fully redundant signals to individually configurable outputs, including selection between several error reporting modes. In SENT mode, the circuit provides enhanced serial messages, including error codes and user-defined values.
