MLX90316 Rotary Position Sensor IC Datasheet Features and Benefits Description Absolute Rotary Position Sensor IC The MLX90316 is a Tria is Rotary Position Sensor providing the absolute angular position of Simple & Robust Magnetic Design a small dipole magnet rotating above the device Tria is Hall Technology surface (end-of-shaft magnet). Programmable Angular Range up to 360 Degrees Thanks to an Integrated Magneto-Concentrator (IMC) on its surface, the monolithic device senses, Programmable Linear Transfer Characteristic in a contactless fashion, the horizontal component Selectable Analog (Ratiometric), PWM, Serial of the applied magnetic flux density. Protocol 12 bit Angular Resolution - 10 bit Angular This unique sensing principle applied to a rotary position sensor results into an impressive Thermal Accuracy robustness of the angular position over the 40 bit ID Number mechanical (airgap, off-axis) tolerances. Single Die SOIC-8 Package RoHS Compliant Dual Die (Full Redundant) TSSOP-16 Package The rotation of this horizontal component is RoHS Compliant sensed over a wide range (up to 360 Deg. - complete revolution) and processed by the on- chip DSP (Digital Signal Processing) to ultimately report the absolute angular position of the magnet either as a ratiometric analog output or as SOIC-8 TSSOP-16 PWM (Pulse-Width Modulation) signal or as a 14- bit data accessible through a 3-pin SPI (serial interface) channel. Applications The output transfer characteristic is fully Absolute Rotary Position Sensor programmable (e.g. offset, gain, clamping levels, Steering Wheel Position Sensor linearity, thermal drift, filtering, range...) to match Pedal Position Sensor any specific requirement through end-of-line calibration. The Melexis programming unit PTC-04 Motor-shaft Position Sensor communicates and calibrates the device Throttle Position Sensor exclusively through the connector terminals (VDD- Float-Level Sensor VSS-OUT).
