Triaxis® mainstream rotary & joystick position sensor IC (SPI) - MLX90427
Product description
The MLX90427 is a monolithic magnetic position sensor IC designed for modern embedded apps with high safety, EMC robustness & stray field immunity. 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 MLX90427 is sensitive to three (Bx, By, and Bz) components of the flux density applied to the IC. This allows the MLX90427 to sense any magnet moving in its surrounding and decode its position through an appropriate signal processing.
The MLX90427 provides versatility to meet diverse application needs, featuring SPI output and four distinct operating modes:
- Rotary 360°
- Rotary 360° SFI (Stray Field Immune)
- Joystick
- Raw data
Moreover, a hybrid mode allows for the combination of these modes, further enhancing its adaptability.
The MLX90427 is intended for Embedded Position Sensor applications (vs. Stand-Alone “Remote” Sensor) for which the output is directly provided to a microcontroller (Master) close to the MLX90427 (Slave). The SPI protocol confirms this intent.
