Melexis — MLX90381 3D Magnetic Pico-Resolver




Melexis MLX90381 3D Magnetic Pico-Resolver

A world’s first that opens a world of possibilities

The Melexis MLX90381 3D Magnetic Pico-Resolver spearheads a world of possibilities for industrial and automotive design engineers. This first-in-the-world device is AEC-Q100/ISO 26262 compliant and delivers outstanding ease of use and superior reliability to its applications in a tiny footprint.

The Melexis MLX90381 3D Magnetic Pico-Resolver is beyond small. Its DFN-6 (2 mm x 2.5 mm) package is suited for sensored mechatronic miniaturization. This device adds the benefits of a small outline and the reliability of analog outputs providing sine and cosine signals.

This ASIL-ready device is programmable at module level and is optimal for rotor position detection. The MLX90381 leverages Melexis’ own Triaxis® Hall technology, providing low latency and fast response, measuring speeds over 50,000 rpm.
