Melexis MLX90425GDC-ABA-600-SP

The MLX90425 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 MLX90425 is sensitive to the differential magnetic field perpendicular to the IC surface (Z-axis). With proper magnetic design, this enables the MLX90425 to decode the absolute position of a rotating coaxial magnet above or below the sensor (e.g., rotational position from 0° to 360°). It enables the design of contactless position sensors, which are frequently required in automotive and industrial applications.

The MLX90425 offers ratiometric analog or pulse width modulation (PWM) output. Thanks to multi-point programmable linearization, programming the sensor after assembling it into the application improves system accuracy.
