Smart Stepper Motor Driver with SPI, UART and Step/Direction (1,2A/1,4A/46V)

The TMC2130 is a high performance driver IC for two phase stepper motors. Standard SPI and Step/Dir simplify communication. TRINAMICs sophisticated stealthChop chopper ensures noiseless operation combined with maximum efficiency and best motor torque. Due to features like stallGuard2 and coolStep energy consumption can be reduced by up to 75%.

Moreover, using the dcStep feature of the TMC2130 high loads can be moved as fast as possible without steploss. Integrated power MOSFETs handle motor currents up to 1.2A RMS (TMC2130-LA) or 1.4A RMS (TMC2130-TA) continuously or 2.5A short time peak current per coil. Protection and diagnostic features support robust and reliable operation. Industries’ most advanced stepper motor driver enables miniaturized designs with low external component count for cost-effective and highly competitive solutions.
