Triaxis® High-Speed Encoder IC - MLX90382
Product description
The MLX90382 is a monolithic magnetic position sensor IC that integrates a Triaxis® Hall magnetic front end, an analog-to-digital converter, a digital hardware for high-speed signal processing and conditioning, and multiple output drivers.
The MLX90382 features 360° stray field immunity (up to 4 kA/m) and is sensitive to three components of the magnetic flux density applied to the IC (i.e. Bx, By, and Bz) as well as a differential magnetic field in the Z-axis. By programming the sensor, the user can select which axis pair will be used to determine an angle. This flexibility, combined with the appropriate magnetic design, allows the MLX90382 to calculate both the absolute and incremental position of any rotating magnet.
MLX90382 offers 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 BLCD motors, 3) a PWM interface, and 4-5) SPI and SSI interfaces with configurable content that support functional safety requirements. Additionally, the SPI protocol includes a multi-slave synchronized readout capability
With 14-bit resolution, differential outputs, and a speed range up to 200k e-RPM, the MLX90382 is ideal for industrial automation, robotics, and e-mobility solutions.
To facilitate development, an Evaluation Board (EVB90382) and a full development kit (DVK90382) are available.
