Description

The MT6835 magnetic encoder module employs Anisotropic Magneto-Resistive (AMR) technology to deliver non-contact, absolute 360° angular position sensing. This principle ensures high accuracy and reliability with minimal wear, even in high-vibration environments. The module outputs raw data via a high-speed SPI interface and provides configurable PWM, ABZ quadrature, and UVW commutation signals for direct motor control.

Designed for seamless integration into servo systems, CNC machinery, and robotics, the encoder features a robust industrial temperature rating and operates across a standard logic voltage range. Its design and pinout make it a functional replacement for AS5048-series encoders, offering enhanced resolution and speed performance for precision motion control applications.

Key Features

  • High-precision 21-bit absolute angle measurement via AMR sensing element.
  • Flexible output configuration for SPI digital readout, PWM duty cycle, ABZ incremental pulses, and UVW Hall-effect emulation.
  • Engineered for high rotational speeds, supporting operation up to 120,000 RPM.
  • Industrial durability with an extended operating temperature range of -40°C to +125°C.
  • Wide supply voltage compatibility from 3.3V to 5.0V DC for versatile system integration.
  • Compact and robust TSSOP-16 surface-mount package for space-constrained designs.
  • User-programmable ABZ resolution (1 to 16384 pulses per revolution) and UVW pole pairs (1 to 16).

Applications

  • High-performance brushless DC (BLDC) motor commutation and speed control.
  • Precision angular position feedback in industrial robotics and CNC rotary tables.
  • Servo drive systems requiring absolute multi-turn position retention.
  • Automated guided vehicles (AGVs) and robotic arm joint angle sensing.
  • Upgrading or replacing AS5048-series encoders in existing motion control designs.

Frequently Asked Questions

What is the difference between the SPI and PWM output modes on the MT6835?

The SPI interface provides full 21-bit digital absolute angle data for high-precision microcontroller reading. The PWM output mode delivers a duty cycle proportional to the angle, suitable for direct analog input or timing measurement, with a configurable 12-bit resolution.

How do I configure the ABZ output resolution for my motor controller?

The ABZ quadrature output resolution is user-programmable from 1 to 16384 pulses per revolution (PPR). Configuration is performed via the SPI command interface, allowing you to set the exact PPR value to match the requirements of your servo drive or motion controller.

What is the purpose of the UVW output, and how is it configured?

The UVW output emulates a 3-phase Hall-effect sensor signal for brushless motor commutation. You can configure the number of electrical pole pairs (from 1 to 16) via SPI to match your specific motor, enabling seamless sensorless FOC (Field-Oriented Control) integration.

What is the operating voltage range, and is 5V logic safe?

The MT6835 operates from 3.3V to 5.0V DC. A 5V supply is fully within specification and ensures compatible logic levels for both the power supply and digital communication lines (SPI, PWM) when interfacing with 5V microcontroller systems.

Can this encoder replace an AS5048A or similar module directly?

Yes, the MT6835 is designed as a performance upgrade and functional replacement for AS5048-series encoders. It offers higher 21-bit resolution, supports the same core interfaces (SPI, PWM, ABZ), and operates at significantly higher speeds (up to 120,000 RPM), making it a direct drop-in upgrade for many applications.
