General Description

The TMR3109 is a contactless, high-precision, and high-speed magnetic rotary encoder sensor, which integrated with tunneling magnetoresistance (TMR) sensors and CMOS digital signal processing circuitry.

The TMR3109 senses the single pole-pair magnet rotation above the chip by TMR sensors, collects the rotating magnetic field signal, transmits it to the digital processing unit, and calculates the rotation angle.

The TMR3109 supports 3-wire and 4-wire SPI working modes, allowing the client MCU to read 23-bit absolute position information through the SPI protocol.

Key Features

  • Tunneling magnetoresistance (TMR) technology.
  • Supply voltage: 3.3 V to 5 V.
  • Supply current: 10 mA (typical).
  • Supports 0° to 360° absolute angle detection.
  • On and off axis measurements.
  • Available in SPI interface.
  • Angular output delay < 2 μs.
  • Angular repeatability < ±0.05°.
  • Speeds up to 40,000 RPM.
  • Auto-calibration function.
