Description: The MT6835 chip is Magnetek's latest fourth-generation magnetic angle encoder IC, a new upgrade from the MT6825. Based on Anisotropic Magnetoresistive (AMR) technology and proprietary signal processing technology, it achieves absolute angle measurement from 0 degree to 360 degree .
The 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 chip's internal 21-bit absolute angle data via an SPI interface supporting clock speeds up to 16MHz. It supports speeds up to 120,000 RPM. The MT6835 chip can be applied to various applications requiring high-speed, high-precision control, such as closed-loop stepper motor control, 2500-line servo motors, and 17-bit absolute servo motor control.
Features:
- Based on AMR technology, providing absolute angle measurement from 0 degree to 360 degree
- Operating voltage: 3.3~5.0V
- Operating temperature: -40 Celsius ~125 Celsius
- Typical linearity deviation: Less than plus-minus 0.5 degree (factory value), Less than plus-minus 0.07 degree (typical self-calibration), Less than plus-minus 0.02 degree (typical NLC self-calibration)
- System latency: 2µs~10µs, supporting speeds up to 120,000 RPM
- Provides a standard 4-wire SPI interface (maximum clock 16MHz) to read 21-bit angle data from the chip
- Incremental output ABZ supports arbitrary resolution from 1 to 16384 lines
- Incremental output UVW supports arbitrary polarity from 1 to 16
- Provides 12-bit PWM output
