Sense Melexis Current Sensors Melexis Triaxis magnetometer EN MLX9042x Series (new)
Triaxis® mainstream 360 rotary SFI position sensor (SENT)
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 perpendicular to the IC surface (Z- axis). This allows the MLX90426, with the correct magnetic design, to decode the absolute position of a rotating on-axis magnet above or below the sensor (e.g. rotary position from 0° to 360°). It enables the design of non- contacting position sensors that are frequently required in automotive and industrial applications.
The MLX90426 provides SENT frames 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.
