The MLX90333 is a Triaxis® position sensor IC able to sense any magnet moving in its surrounding through the measurement and the processing of the three spatial components of the magnetic flux density vector. Top features Absolute 3D position sensor IC Simple and robust magnetic design Triaxis® Hall technology Product description The MLX90333 is a Triaxis® position sensor IC able to sense any magnet moving in its surrounding through the measurement and the processing of the three spatial components of the magnetic flux density vector (i.e. Bx, By and Bz). The horizontal components (Bx and By) are sensed thanks to an IMC while the vertical component (Bz) is sensed through conventional Hall plate. The MLX90333 features a 3D magnetometer mode for which the 3D information of the magnetic flux density are reported through SPI. The MLX90333 features also a contactless position sensor mode suitable for rotary position sensor (through-shaft magnet), linear stroke position sensor (magnet displacement parallel to the device surface) and for 3D/"Joystick" position sensor. The processed position information is ultimately reported as a ratiometric analog output or as PWM signal. In case of 3D/"joystick" mode, the device features two independent outputs. A 3-pin SPI (serial interface) mode is also available to transfer the position information to a host-controller. The output transfer characteristic is fully programmable (e.g. offset, gain, clamping levels, linearity, thermal drift, filtering, range...) to match any specific requirement through end-of-line calibration.
