The MLX90380 single IC solution is suitable for high-speed rotating applications, such as automotive electrical power steering motors and superchargers, due to its 2μs sampling and 8μs output refresh rates. The chip provides Sine and Cosine analog ratiometric outputs while other options include the ability to select sensitivity from 10mT to 70mT and three different configurations for the magnetic field axis. What's more, the IC can be mounted in either end-of-shaft or through-shaft applications. By simply selecting the correct option code, designers are now able to measure rotation and position at any point along a shaft by using a ring magnet in conjunction with the MLX90380.
The MLX90380 operates from -40 to +150°C for use in harsh applications. A standard version is available in a small SOIC-8 package and a fully redundant version is provided in a SOIC-16 package. For PCB-less applications, such as direct mounting in a motor, a DMP-4 package is available. Also available is ISO26262 documentation to support safety-critical automotive applications.
