TMC2209 Stepper Motor Driver Module

[Click the image to enlarge it]

The TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. The driver has a maximum output capacity of 28 V and ± 2 A. It can operate bipolar stepper motors from 1 to 1/256 step modes. TMC2209 uses StealthChop2 technology for silent motor operation.

TMC2209 Stepper Driver Module Specification

  • Max. Operating Voltage: 28 V
  • Min. Operating Voltage: 4.75 V
  • Max. Current Per Phase: 2 A
  • Board Width 0.6", Board Height 0.8"

Note: Complete Technical Details can be found at the TMC2209 datasheet given at the end of this page.

 

Special Features

  • StealthChop2: No-noise, high-precision chopper algorithm for inaudible motion and inaudible standstill of the motor.
  • StallGuard4: Sensorless homing safes end switches and warns in case of motor overload.
  • SpreadCycle: High-precision cycle-by-cycle current control for highest dynamic movements.
  • CoolStep: Uses StallGuard measurement in order to adapt the motor current for best efficiency and lowest heat-up of motor and driver.
  • MicroPlyer: Microstep interpolator for obtaining full 256 microstep smoothness with lower resolution step inputs starting from fullstep.

How to Use TMC2209 Driver Module

Interfacing diagram for TMC2209 is shown below. Pinout and working of TMC2209 is same as A4988 and DRV8825 but it uses StealthChop2 technology and other special features to operate the motor silently and effectively.

How to Use TMC2209 Driver Module

 

As shown in above diagram, DIR, STEP pins of module is connected with Microcontroller. STEP pin used to control the steps while DIR pin is used to control direction. TMC2209 has StealthChop2 technology that ensures the noiseless operation, maximum efficiency and best motor torque. TMC2209 has 9 step resolution from 1to 1/256 steps. You can change the step resolution using the microstep pins (MS1 & MS2). By setting appropriate logic levels to these pins we can set the motors to one of the nine step resolutions. TMC2209 uses MicroPlayer technology for obtaining full 256 microstep with lower resolution step inputs starting from fullstep. It is commonly used in controlling the NEMA series stepper motors like NEMA17, NEMA23, NEMA34
