Product Overview

The MT6835 is a high-resolution, high-precision magnetic angle encoder IC from MagnTek, utilizing advanced Anisotropic Magnetoresistance (AMR) technology. It offers absolute angle position detection from 0 to 360 degrees with a core angular resolution of 21 bits, supporting rotational speeds up to 120,000 RPM. The chip features a low output delay of 2-10 microseconds and provides client-side automatic non-linear calibration for enhanced accuracy (<0.07 INL). It operates reliably within a temperature range of -40 to 125 and supports multiple output modes including incremental ABZ, incremental UVW, PWM absolute, and 4-wire SPI bus output. Applications include absolute angle position sensing, DC brushless motor control, servo motor control, and closed-loop stepper motor control, serving as a potential replacement for traditional photoelectric encoders.
