The MT6835 chip is the latest fourth-generation magnetic angle encoder IC, that is, the new upgrade chip of MT6825, based on anisotropic magnetoresistive (AMR) technology and proprietary signal processing technology to achieve absolute angle measurement of 0°~360°.
The chip consists of a pair of AMR Wheatstone bridges and signal processing ASIC circuits. With the rotation of the magnetic field parallel to the surface of the chip, the chip can output angular signals such as ABZ/UVW, PWM, etc., and the user can also read the 21-bit absolute angle data inside the chip through the SPI interface that supports up to 16MHz clock. It supports speeds up to 120,000 rpm. The MT6835 chip can be applied to various application scenarioses with high-speed and high-precision control requirements, such as closed-loop stepper motor control, 2500-line servo and 17-bit absolute servo motor control.
