MLX90324

 

 

 The MLX90324 is a Triaxis® Rotary Position Sensor providing the 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 360º - 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 ratio-metric analog output or as PWM (Pulse-Width Modulation) signal or as a SAE-J2716/SENT (2007) telegram. 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 MLX90324 targets and is used in a myriad of non-contacting rotary position sensor applications which are frequently seen in automotive and industrial systems.
The MLX90324 is similar to the MLX90316 in many ways but its thermal stability and the SENT protocol make it suitable for under-the-hood applications. The device is available in single and dual redundant implementations to cost-effectively address the full range of applications, including safety critical sensing requirements.
