FI6901

FI6901 is a sensor chip based on 3D Hall technology to detect rotational and linear position in the non-contacting way,which can support SAE-J2716/SENT agreement. It can detect the absolute position of the moving magnet ( a rotated angle position from 0 to 360 degrees or a linear movement and stroke) by sensitively detecting the magnetic flux density in three directions in the magnetic field (i.e. Bx, BY, and Bz)All the parameters of chip’s output transmission characteristic are programmable, such as offset, gain, clamp level, linearity, thermal drift, filter, range, etc. Users can calibrate the chip’s offline with the programmers from Flying Fairy based on application’s requirements.
