Melexis MLX90510 High-Speed Inductive Resolver IC

Melexis MLX90510 High-Speed Inductive Resolver IC is designed for absolute rotary motion/position sensing in safety-critical automotive applications. The MLX90510 specifications support e-machine types of applications directly and minimize the ECU effort needed to get best-in-class accuracy under extreme mechanical and electrical conditions.

The Melexis MLX90510 is built to control an inductive transducer, process the captured analog sensor signal, and supply differential Sine and Cosine outputs. The inductive sensor operation is established on the inductive coupling between a transmitting coil, the target, and three receiver coils.
