TMC2208 are quieter drivers designed for use with two-phase stepper motors. Their pin layout is compatible with older driver models.
TRINAMIC's innovative StealthChop2 chopper ensures smooth and noiseless operation with maximum efficiency and best motor torque. The fast current control and optional combination with SpreadCycle technology will enable dynamic movement with high precision. Built-in PowerMOSFET power transistors can handle motor current up to 1.4 A RMS.
Protection and diagnostic functions ensure reliable operation. Clear UART interfaces allow easy setup and control.
This series of STEP/DIR drivers is among the most advanced in the field. It offers noiseless, accurate and economical operation.
