 The MLX90333 is a Triaxis® Position Sensor able to sense any magnet moving in its surrounding through the measurement and the processing of the 3 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 Integrated Magneto-Concentrator (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 ratio-metric analog output or as PWM (Pulse-Width Modulation) signal. In case of 3D/"Joystick" mode, the device features 2 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. The Melexis programming unit PTC-04 communicates and calibrates the device exclusively through the connector terminals (Vdd-Vss-Out).
The MLX90333 targets and is used in a myriad of non-contacting position sensor applications which are frequently seen in automotive and industrial systems. In particular, it is suitable for linear displacement and "joystick" sensing applications.
