Description

MT6835GT Magnetic Encoder Chip 1~16384 Lines ABZ.1~16 Pairs of Poles UVW21 Bits

Product Model: MT6835GT

Manufacturer: MagnTek

describe:

The MT6835 chip is the fourth-generation magnetic angle encoder IC newly launched by MagnTek, which is a new upgraded chip of the MT6825. It is based on Anisotropic Magnetoresistive (AMR) technology and proprietary signal processing technology. ° absolute angle measurement.

The chip consists of a pair of AMR Wheatstone bridges and a signal processing ASIC circuit. With the rotation of the magnetic field parallel to the chip surface, the chip can output ABZ/UVW, PWM and other angle signals, and users can also read the 21bit absolute angle data inside the chip through the SPI interface that supports up to 16MHz clock. Supports up to 120,000 rpm. The MT6835 chip can be used in various application scenarios that require high-speed and high-precision control, such as closed-loop stepper motor control, 2500-line servo, and 17-bit absolute value servo motor control.
