MT6835 Magnetic Encoder 21bit High Precision 4-Wire SPI AB16384 Pulse SPI ABZ Mode for Stepper Brushless Motor

The MT6835 chip is a fourth-generation magnetic angle encoder IC, a major upgrade from the MT6825. Based on Anisotropic Magnetoresistive (AMR) technology and proprietary signal processing technology, it achieves absolute angle measurement from 0° to 360°.

The chip consists of a pair of AMR Wheatstone bridges and a signal processing ASIC. With the rotation of a magnetic field parallel to the chip surface, the chip outputs ABZ/UVW, PWM, and other angle signals. Users can also read the 21-bit absolute angle data from the chip via an SPI interface with a clock speed up to 16MHz.

Supports speeds up to 120,000 RPM.

The MT6835 chip is suitable for various applications requiring high-speed, high-precision control, such as closed-loop stepper motor control, 2500-line servo motor control, and 17-bit absolute value servo motor control.
