TMC2208 vs. TMC2209 Overview

The TMC22XX are ultra-silent motor driver ICs for two-phase stepper motors. Their pinning is compatible with a number of legacy drivers. TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation, maximum efficiency and best motor torque. Its fast current regulation and optional combination with SpreadCycle allow for highly dynamic motion. Integrated power MOSFETs handle motor current up to 1.4 ARMS. Protection and diagnostic features support robust and reliable operation. A simple to use UART interface opens up more tuning and control options. Application-specific tuning can be stored in OTP memory. Industries’ most advanced STEP/DIR stepper motor driver family upgrades design to noiseless and most precise operation for cost-effective and highly competitive solutions.

TMC2209 pinning is compatible with a number of legacy drivers as well as with the TMC2208. TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation, maximum efficiency and best motor torque. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. Stallard for sensorless homing.

The TMC22xx family scores with power density, integrated power MOSFETs, smooth and quiet operation, and a congenial simplicity. The TMC22xx covers a wide spectrum of applications from battery systems to embedded applications with up to 2 A motor current per coil. TRINAMICs unique chopper modes SpreadCycle and StealthChop2 optimize drive performance. StealthChop reduces motor noise to the point of silence at low velocities. Standby current reduction keeps costs for power dissipation and cooling down. Extensive support enables rapid design cycles and fast time-to-market with competitive products.

TMC2209 Application Circuit

The TMC22xx family of stepper drivers is intended as a drop-in upgrade for existing low-cost stepper driver applications. Its silent drive technology StealthChop enables non-bugging motion control for home and office applications. A highly efficient power stage enables high current from a tiny package.

The TMC2208 requires just a few control pins on its tiny package. They allow the selection of the most important setting: the desired micro step resolution. A choice of 2, 4, 8, 16 or 32 micro steps adapts the driver to the capabilities of the motion controller. Some package options also allow chopper mode selection by pin. The TMC2209 requires just a few control pins on its tiny package. It allows the selection of the most important setting: the desired micro step resolution. A choice of 8,16, 32 or 64 micro-steps, or from full step up to 1/256 step adapts the driver to the capabilities of the motion controller.

TMC2208 vs. TMC2209 Conclusion

Both the TMC2208 and TMC2209 support 1/256 stepping, both interpolated and native. They are both using StealthChop V2 for whisper-quiet printing. The TMC2208 was chosen over the TMC2209 for a variety of reasons related to the machines for which the board is designed and the design cycle of our board. Because they both use the same basic technologies to regulate the motors and have the same noise levels, there are no differences in print quality between 2208 and 2209.
