Melexis MLX90333KDC-BCH-000-SP

The MLX90333 is a Tria⊗is® 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 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 (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 (VDDVSS-OUT).
