Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. High energy efficiency from TRINAMICs CoolStep technology delivers further cost savings in related systems such as power supplies and cooling. STEPROCKER The driver stage shown uses 6A-capable dual MOSFETs. All cooling requirements are satisfied by passive convection cooling. The stepRocker is supported by the motioncontrol-community, with forum, applications, schematics, open source projects, demos etc.: Layout with 6A MOSFETs TMCM-MODULE FOR NEMA 11 STEPPER MOTORS This miniaturized power stage drives up to 1.2A RMS and mounts directly on a 28mm-size motor. Tiny TSOP6 dual MOSFETs enable an ultra-compact and flexible PCB layout. Miniaturized Layout TMC262-EVAL DEVELOPMENT PLATFORM This evaluation board is a development platform for applications based on the TMC262C. External power MOSFETs support drive currents up to 4A RMS and up to 40V peak supply voltage. The evaluation board system based on the CPU board LANDUNGSBRCKE features an USB interface for communication with the learning and development control software TMCL-IDE running on a PC. The control software provides a user-friendly GUI for setting Layout for Evaluation control parameters and visualizing the dynamic response of the motor.
