Melexis MLX90382 Magnetic Position Sensor ICs
Melexis MLX90382 Magnetic Position Sensor ICs combine a Triaxis® Hall magnetic front end, an analog-to-digital converter, digital hardware for high-speed signal processing and conditioning, as well as several output drivers. The MLX90382 is susceptible to three components of the magnetic flux density applied to the IC (i.e., Bx, By, and Bz) and a differential magnetic field in the Z-axis. By programming the sensor, the user can choose which axis pair will be used to specify an angle. The flexibility, incorporated with the suitable magnetic design, enables the MLX90382 to calculate both the absolute and incremental position of any rotating magnet.
The Melexis MLX90382 Magnetic Position Sensor ICs are factory-trimmed for immediate use. For tighter accuracy, end-of-line calibration includes multi-point linearization and self-calibration. In-operation drift tracking ensures high-speed angle accuracy despite assembly tolerances, temperature fluctuations, and aging.
The MLX90382 Sensor ICs offer five output modes: 1) an industry-standard single-ended and differential ABI interface for incremental angular output, 2) a single-ended and differential UVW signal emulation for BLDC motors, 3) a PWM interface, and 4-5) SPI and SSI interfaces with configurable content that help meet functional safety requirements. Furthermore, the SPI protocol contains a multi-slave synchronized readout capability.
