Rotary position sensor MLX90377

linearnon-contactmagnetic

The MLX90377 is a flexible magnetic position sensor IC conceived for high performance automotive applications. It senses three axes (i.e. X, Y, Z) from a magnet to measure rotary or linear motion. Top features 4 supported Output modes (by version) Programmable Linear Transfer Characteristic Robustness against stray-field up to 5mT Product description The MLX90377 is a monolithic magnetic position sensor IC. It consists of a Triaxis® Hall magnetic front end, an analog to digital signal conditioner, a DSP for advanced signal processing and an output stage driver. The MLX90377 is sensitive to the three components of the magnetic flux density applied to the IC (i.e. Bx, By and Bz). This allows the MLX90377 with the correct magnetic circuit to decode the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees or linear displacement). It enables the design of non-contacting position sensors that are frequently required for both automotive and industrial applications. The MLX90377 provides 4 output modes. Firstly, the IC supports (fast) SENT frames encoded according to a Secure Sensor format. The output delivers enhanced serial messages providing error codes, and user-defined values. Through programming, the MLX90377 can also be configured to output Short PWM (SPC), PWM (Pulse Width Modulated) signal or an analog ratiometric signal. ASIL Readiness - Melexis The MLX90377 has been especially conceived for demanding automotive applications and to bring new functionalities:
