The FH3D12 is a dual 3D Hall sensor based on the Fraunhofer HallinOne® technology from the Fraunhofer Institute for Integrated Circuits, IIS. This versatile magnetic field sensor uses the pure Hall effect principle without magnetizable materials. The FH3D12 offers high dynamic magnetic range and precise 3D magnetic field measurements at two positions with a planar IC in a stamped MLF-16 5x5x0.9mm with 0.8mm pitch. Supports applications that are robust to stray fields through the use of magnetic field gradients.
Applications:
- 3D position determination (joystick)
- Current measurement
- Linear position determination (axial/orthogonal and axial/parallel)
- Angle measurement (on axis and off axis)
- Mapping magnetic fields
Characteristics:
- Dual 3D Hall sensor with 2mm distance
- Measuring range full scale from ~10mT to ~1.5T
- Measuring rate up to 20kHz at 12Bit or 1.8kHz at 16Bit resolution
- Supply voltage 3.0V…3.6V
- Temperature range -40°C … 125°C
- Temperature sensor for tracking system deviations
- Software defined sensor:
- Each sensor element can be independently configured in terms of measuring range and rate
- Measuring sequence (active sensor elements and measurement sequence)
- Integrated excitation coils
- Magnetic calibration without the need for magnetic setup
- Magnetic self-test during operation
- Diagnostic functions for error detection
- SPI interface
