DESCRIPTION
The TMC5072 is a dual high performance
stepper motor controller and driver IC
with serial communication interfaces. It
combines flexible ramp generators for
automatic target positioning with
industriesâ 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.
