HallinOne®: Integrated Magnetic Field Sensor

With the integrated 3D Hall sensor technology HallinOne®, all three components of the magnetic field vector can be detected with one sensor chip. While conventional Hall sensors are only sensitive to magnetic fields oriented perpendicular to the chip surface, the HallinOne® sensor also measures magnetic fields that are aligned parallel to the chip surface. The integration of sensors, together with analog and digital signal processing, enables low-noise operation and the use of highly efficient algorithms, e.g. for contactless position measurement in one chip.

FH6D04 – RISC-V-powered Quad 3D Hall Sensor

Discover the FH6D04, a powerful RISC-V-powered quad 3D Hall sensor built on Fraunhofer's innovative HallinOne® technology. This versatile magnetic field sensor operates purely on the Hall effect principle, without the need for magnetizable materials. It offers a high dynamic range and precise 3D magnetic field measurement at four positions – all in a compact 5.0 x 4.0 x 0.6 mm WLCSP package. By utilizing magnetic field gradients, the FH6D04 is also ideal for applications requiring robust stray field resistance.

Evaluation kits are available on request for companies wishing to test the FH6D04.
