Next-generation Triaxis position sensor IC

Next-generation Triaxis position sensor IC

By eeNews Europe

The series consists of the MLX90371 and MLX90372 for absolute position measurement for automotive applications. Both devices integrate a Triaxis Hall magnetic front-end, an analogue to digital signal conditioner, a DSP and an output stage driver. The sensors can measure magnetic flux in the x, y and z planes, facilitating the decoding of the absolute rotary or linear position of any moving magnet, enabling the design of non-contact position sensors. The MLX90371 has analogue or PWM output and the MLX90372 has SENT (SAE J2716 rev Apr 2016) or PWM output.

The sensors are robust against stray fields up to 4kA/m (or 5mT), the levels required by many major automotive manufacturers. Their ability to operate with a reduced magnetic field means that smaller and lower-cost magnets can also be used.

The MLX90372 has an additional input pin to integrate other sensors, which allows an additional signal to be transmitted using the SENT output. The sensors are available in several versions for rotary and linear motion sensing and are a drop-in replacement for the MLX90364, MLX90365, MLX90366 and MLX90367. A PCB-less dual mould package (DMP) can integrate directly into an assembly without requiring a printed circuit board.
