Product description
The MLX90380 is a fast pre-programmed magnetic resolver IC for brushless motors. It is ideally suited to automotive applications as well as other applications that need fast position readouts.
Its ability to measure the absolute angle enables more efficient and safer motor control algorithms such as field oriented control algorithms. Fast in this case means 2μs sampling per field component, 4μs for two components, and 8μs output refresh rates.
The MLX90380 provides sine and cosine analog ratiometric outputs. Its option code includes the ability to select sensitivity from 10mT to 70mT and five different configurations for the magnetic field axis. Flexible mechanical designs are possible as designers can select the field component to be measured. As such, it is even possible to design off axis magnetic readouts.

Fast pre-programmed magnetic resolver IC
With an update frequency of 4us, the MLX90380 is the fastest magnetic resolver IC based on Triaxis® technology. Additionally, this product gives mechanical designers a lot of design flexibility. It supports end-of-shaft applications. You can position the IC even parallel to the shaft. And you can position the IC next to the shaft, the so-called off axis.
Magnetic pico-resolver IC (Sin/Cos)
The MLX90381 is a 3D magnetic resolver IC measuring rotational speeds of 50’000 e-rpm. It is optimized for robust motor design: smallest footprint, programmable at module level, cost-effective and ASIL-ready.
