Melexis MLX90517 High-Speed Inductive Resolver IC

Melexis MLX90517 High-Speed Inductive Resolver IC is developed for e-machines (BLDC, PMSM, PMSR) used as traction or auxiliary motors (steering, braking). The MLX90517 accurate inductive high-speed resolver interface offers a connection for an inductive transducer and supplies raw sine and cosine signals, which the ECU must compensate for before angle calculation. The Melexis MLX90517 (off-chip calculation) complements the MLX90510 (on-chip calculation).
