BLOCK DIAGRAM
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 (QFN package) / 1.4A RMS
(TQFP) 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.
