MT6835 Magnetic Encoder Module 21-Bit High Precision PWM/SPI Interface compatible with Brushless Motor Replace compatible with AS5048 B

The MT6835 chip is fourth-generation magnetic Angle encoder IC, an upgraded version of the MT6825, based on Anisotropic Magnetoresistive. The AMR (abbreviated as AMR) technology and proprietary signal processing technology have achieved absolute Angle measurement from 0° to 360°. This chip consists of a pair of AMR Wheatstone Bridges and a signal processing ASIC circuit. As the magnetic field parallel to the chip surface rotates, the chip can output Angle signals such as ABZ/UVW and PWM. Users can also read the 21-bit absolute Angle data inside the chip through the SPI interface that supports a clock as high as 16MHz. Supports a maximum rotational speed of 120,000 revolutions per minute. The MT6835 chip can be applied to various scenarios with high-speed and high-precision control requirements, such as closed-loop stepper motor control, 2500-line servo, and 17-bit absolute value servo motor control, etc. Based on AMR technology, it provides absolute Angle measurement from 0° to 360° Operating voltage: 3.3-5.0V Operating temperature: -40℃ to 125℃ Typical values of linearity deviation Less than ±0.5° (factory value), typical values of linearity deviation Less than ±0.07° (typical value self-calibration), typical values of linearity deviation Less than ±0.02° (typical NLC self-calibration) The system delay is 2us to 10us, and it can support a maximum rotational speed of up to 120,000 revolutions per minute It provides a standard 4-wire SPI interface (with a maximum clock of 16MHz) to read 21-bit Angle data inside the chip The incremental output ABZ supports any resolution from 1 to 16384 lines The incremental output UVW supports any pair from 1 to 16 It provides a 12-bit PWM output Specifications: B: SPI+AB:16384 Color: Black Material: PCB Package Contents: 1 * Magnetic Encoder 1 * Magnet Only the above package content, other products are not included.
