The MLX90422 is a magnetic position sensor designed for use in cost-sensitive automotive applications including powertrain actuators, pedal positioning, fuel level gauges and transmission systems, though also suitable for industrial implementations. The MLX9042x devices have superior capabilities in terms of functional safety, Absolute Maximum Ratings (AMR) and electromagnetic compliance (EMC) characteristics. They also support operating temperature up to 160 °C.

The MLX90422 is pin-to-pin compatible with the previous generations of Triaxis® position sensor ICs. The MLX90422 is a monolithic magnetic position processor ICs. 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 MLX90422 is sensitive to the three components of the magnetic flux density applied to the ICs (i.e. Bx, By and Bz). This allows the MLX90422 with the correct magnetic circuit to decode the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees). It enables the design of non-contacting position sensors that are frequently required for both automotive and industrial applications.

The MLX90422 supports rotary or linear motions, with a SENT output. SENT frames are encoded according to a Single Secure Sensor A.3 (H.4) or Dual Throttle Position Sensor A.1 (H.1) format. The circuit delivers enhanced serial messages providing error codes, and user-defined values. Programming the sensor, after assembly into the application, increases the accuracy of the system thanks to the multi-point programmable linearization function. The MLX90422 is compatible with the PTC-04 (DB-HALL06) for mass-production programming.
