The MLX90340 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to the IC surface. Top features Triaxis® Hall technology On-chip signal processing for robust absolute position sensing ASIL-A capable, Safety Element out of Context (SEooC) Product description This unique sensing principle applied to a position sensor IC results into an impressive robustness of the position signal over the mechanical (airgap, off-axis) tolerances. The rotation of this horizontal component is sensed over a wide range (up to 360º) and processed by the on-chip digital signal processing (DSP) to ultimately report the absolute angular position of the end-of-shaft magnet. Alternatively, through measuring individually the horizontal and vertical components, the MLX90340 is able to address linear stroke (displacement) position sensors and also absolute rotary position sensors with a through-shaft magnet. The MLX90340 reports either a ratiometric analog output or a pulse-width modulation (PWM) signal. From sensing and reporting perspectives, the MLX90340 is an extremely versatile IC for any stand-alone remote position sensor application. 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). Additionally, the MLX90340 is offered in four different factory-programmed analog versions compatible with 90º, 180º, 270º and 360º rotary end-of-shaft applications.
