MT6620：Magnetic Encoded Chips - Off-axis magnetic angle encoded ICs

The MT6620 is sensor chip for off-axis angle and position sensing based on fixed pole Hall magnetic sensing technology. When the magnetic scale or magnetic ring corresponding to the pole distance of 2mm passes above the chip Hall array, the chip can induce the positive and cosine voltage signals that change with the angle position through the Hall principle, and obtain the corresponding position and angle data after subsequent processing. The MT6620 provides an incremental ABZ output similar to a traditional optical encoder, with a maximum resolution of 2500 pulses/magnetic counter or 10,000 steps/magnetic counter. At the same time, MT6620 also provides incremental UVW output, and the resolution supports 1~63 pairs/magnetic pairs. The core performance improvement of MT6620 is that it provides a convenient self-calibration mode for the client (no data interaction required), through which various nonlinearities caused by the unsatisfactory magnet and the deviation of the structure installation can be compensated, so as to greatly improve the linearity.
