Melexis MLX90381
The MLX90381, Triaxis® pico-resolver, is a monolithic contactless sensor IC sensitive to the flux density applied in three dimensions (X, Y, Z) to the IC. With its 3.3V and 5V supply, high speed, small size, and flexible configuration the MLX90381 is ideal for use in motor control applications when paired with a suitable microcontroller. With a wide operating temperature and magnetic flux density range, the MLX90381 can resolve the angular position of a rotating axis over 360 degrees in many industrial and automotive applications.| Part No. | MLX90381 |

DESCRIPTION
Two, selectable, axes can be mapped to the two high-speed analog outputs allowing the MLX90381 to be used for on-axis and off-axis (through-shaft) position sensing when paired with a moving permanent magnet. With a low response time and latency, the MLX90381 can measure rotational speeds of more than 50’000 RPM.
