The MLX90426 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. 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 MLX90426 is pin-to-pin compatible with the previous generations of Triaxis® position sensor ICs. The MLX90426 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 MLX90426 is sensitive to the differential magnetic field in the Z-axis. This allows the MLX90426 with the correct magnetic circuit to decode the absolute position of a rotating on-axis magnet above or below the sensor (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 MLX90426 offers up to 5 mT stray field immunity and supports 360° rotary motion 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 MLX90426 is compatible with the PTC-04 (DB-HALL06) for mass-production programming.
