DESCRIPTION
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. coolStep allows
reducing energy consumption by up to
75%. dcStep drives high loads as fast as
possible without step loss. 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.
