DESCRIPTION
The TMC2041 is a compact, dual stepper
motor driver IC with serial interfaces for
configuration and diagnostics. It is pin
compatible to the fully featured TMC5041
and TMC5072 drivers with internal mo-
tion controller. The TMC2041 is intended
for all applications, where an internal
motion controller is not desired, and
ramping is done in a microcontroller.
Based on TRINAMICs high-performance
spreadCycle chopper, the driver allows
precise and smooth motor operation. It
offers coolStep for energy savings and
stallGuard for sensorless stall detection.
The complete set of protection and
diagnostic functionality ensures reliable
operation. High integration, high energy
efficiency and a small form factor enable
miniaturized and scalable systems for
cost effective solutions.
