High speed magnetic angle encoder IC
Magnetic Angle Encoder IC - High speed magnetic angle encoder IC
MT6701

Description 

MT6701 is MagnTek’s new generation angle encoder IC based on Hall-Sensing technology. MT6701 is sensitive to the magnetic flux which is perpendicular to the IC surface, with the rotating magnet which is cylindrical diametrically magnetized with one pole-pair, MT6701 outputs angle data with 0~360°full range. MT6701 can provide incremental ABZ/UVW output, absolute Analog/PWM output and I²C/SSI digital interface.

In addition to the rotation angle output, MT6701 provides an additional ‘PUSH’ output, so a button with push function could be realized by a single chip of MT6701.
