3D Magnetic Field Sensor Technology on One Chip
The integrated 3D Hall sensor technology HallinOne® allows 3-axis magnetic field measurement with one sensor chip. Thus, low cost contactless position measuring systems can be implemented. Conventional Hall sensors are only sensitive against magnetic fields perpendicular to the chip surface. Our Hall sensor, however, is able to measure also magnetic fields parallel to the chip surface.
For each of the three magnetic axes the sensor chip has a separate sensor. The digitalization of the measured values is integrated on the sensor chip and allows for connecting the chip directly to a computer or micro controller. No additional process steps are required to produce the HallinOne® sensor cost effectively in standard CMOS technology, leading to a low series price.
