DESCRIPTION
The TMC5041 is a cost-effective dual
stepper motor controller and driver IC
with serial communication interface. It
combines flexible ramp generators for
automatic target positioning with
industries’ most advanced stepper motor
drivers. Based on TRINAMICs
sophisticated stealthChop chopper, the
driver ensures absolutely noiseless
operation combined with maximum
efficiency and best motor torque. High
integration, high energy efficiency and a
small form factor enable miniaturized
and scalable systems for cost effective
solutions. The complete solution reduces
learning curve to a minimum while
giving best performance in class. This
ensures a highly competitive solution.
