Product Profile

TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. Its continuous drive current is 2A and peak current is 2.8A. Compared with TMC2208, the driving current of this IC is not only improved by 0.6a-0.8a, but also this IC increases the function of locked-motor test.

The Flexible microPlyer interpolation unit can provide 256 microsteps. Stallguard4™locked-motor test can provide an abnormal signal when the motor rotates abnormally. CoolStep™ current dynamic control can save 75% energy. The sinusoidal control can be perfectly realized even in the system with limited pulse frequency. Since stealthChop2 ™ ultra-quiet technology is widely used in 3D printing, the design of these components is also compatible with existing 3D printer electronic devices, and it eliminates the expensive cost of redesigning.The module has a standard step/dir interface, it's easy to use.
