APPLICATION EXAMPLES: HIGH FLEXIBILITY – MULTIPURPOSE USE
The TMC2041 scores with power density and sensorless homing. It features serial interfaces for advanced
monitoring and configuration options. The small form factor keeps costs down and allows for miniaturized
layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-
to-market with competitive products. High energy efficiency and reliability deliver cost savings in related
systems such as power supplies and cooling.
STEP/DIR FOR UP TO TWO STEPPER MOTORS
The stepper motor driver
outputs are switched in
Step/Dir
parallel. This way, up to
2.2A RMS motors can be
driven.

TMC2041-EVAL EVALUATION BOARD
EVALUATION & DEVELOPMENT PLATFORM
The TMC2041-EVAL is part of TRINAMICs universal
evaluation board system which provides
a
convenient handling of the hardware as well as a
user-friendly software tool for evaluation. The
TMC2041 evaluation board system consists of three
parts: STARTRAMPE (base board), ESELSBRÜCKE
(connector board including several test points), and
TMC2041-EVAL.
