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.
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. This new option is especially optimized for 360° rotary applications requiring dual die and some strayfield immunity.
The MLX90376 is compatible with the PTC-04 (DB-HALL06) for mass-production programming.
Application Examples:
- Throttle Position Sensor
- Ride Height Position Sensor
- Float-Level Sensor
- Steering Wheel Position Sensor
