The MLX90371 series
Building upon the long legacy of Triaxis® sensors, the MLX90371 brings substantial improvements over the previous generation. The new stray field immune mode drastically reduces or even eliminates the effect of stray fields from other magnets or current carrying conductors found in electrified vehicles and supports both on-axis rotary or linear motion with a four-pole or two-pole magnet, respectively.
For customers not requiring stray field compatibility, or those requiring off-axis sensing, the MLX90371 is also backwards compatible in both pinout and magnetic design to the MLX90364 and MLX90365 that utilize a two-pole magnet. Additionally many aspects of the sensor are improved including EMC capability, higher temperature operation (up to 160°C ambient), and thermal drift performance. Finally these sensors offer ASIL-B (SEooC) readiness and fully-redundant dual-die package option.
