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 and 4μs for two components.
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.

Salmon represent our magnetic sensors
because of the use magnetism for their sense
of direction. This sense of direction is so strong
they even can climb waterfalls.
