Overview
The MLX90363KDC-ABB-000-RE, produced by Melexis Technologies NV, is a monolithic magnetic sensor IC that utilizes the Triaxis® Hall technology. This device is part of the second and a half generation of Triaxis® position sensor ICs and is designed for various position sensing applications, including rotary, linear, and joystick configurations. The MLX90363 senses the three spatial components (Bx, By, Bz) of the applied magnetic flux density, enabling robust position sensing over mechanical tolerances such as airgap and off-axis variations.
The IC features on-chip signal processing, high-speed serial interface (SPI compatible with full duplex), and enhanced self-diagnostics. It is compatible with both 5V and 3.3V applications and offers a 14-bit output resolution. The device is available in single die (SOIC-8 package) and dual die (TSSOP-16 package) configurations, both of which are lead-free and RoHS compliant.
