linearnon-contactmagnetic

The MLX90376 is an absolute magnetic position sensor IC handling 360° rotary automotive applications with stray field immunity. It offers a dual-stacked die PCB-less version and supports system integration up to ASIL D. Top features 4 supported output modes (by version) Programmable linear transfer characteristic Robustness against stray magnetic field up to 5 mT (4 kA/m) as per ISO 11452-8. Stray-field immune angle sensing up to 360° Product description The MLX90376 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. SMP-4 (VD), dual stacked-die in Single Mold PCB-less solution The MLX90376 is sensitive to the three components of the magnetic flux density applied to the IC (i.e. Bx, By and Bz). This allows the MLX90376 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 noncontacting position sensors that are frequently required for both automotive and industrial applications. The MLX90376 provides 4 output modes. Firstly, the IC supports (fast) SENT and SPC frames encoded according to a Secure Sensor format. The output delivers enhanced serial messages providing error codes, and user-defined values. Through programming, the MLX90376 can also be configured to output a PWM (Pulse Width Modulated) or an analog ratiometric output. The MLX90376 introduces a dual stacked-die version in a Single-Mold-Package (SMP), a PCB-less solution.
