Description:
The MLX90316 is a Tria⊗is® Rotary Position Sensor providing the absolute angular position of a small dipole magnet rotating above the device surface (end-of-shaft magnet). Thanks to an Integrated Magneto-Concentrator (IMC) on its surface, the monolithic device senses, in a contactless fashion, the horizontal component of the applied magnetic flux density. This unique sensing principle applied to a rotary position sensor results into an impressive robustness of the angular position over the mechanical (airgap, off-axis) tolerances. The rotation of this horizontal component is sensed over a wide range (up to 360 Deg. - complete revolution) and processed by the onchip DSP (Digital Signal Processing) to ultimately report the absolute angular position of the magnet either as a ratiometric analog output or as PWM (Pulse-Width Modulation) signal or as a 14- bit data accessible through a 3-pin SPI (serial interface) channel. 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).
