产品详情

The TMC3241-EVKIT includes the TMC3241-EVAL board, the Eselsbruecke, and Landungsbruecke interface boards, which operate together as part of the ADI Trinamic™ TMCL ecosystem.

The TMC3241 is a smart, high-performance, single-axis 3-phase stepper motor controller and driver IC. It fully integrates three 65V H-bridges, capable of driving motors with up to 4.2A_RMS (5.94A_FS) current, together with lossless integrated current sensing (ICS), eliminating the need for external MOSFETs and current-sense resistors. The resulting compact solution reduces system complexity and printed circuit board (PCB) area.

The integrated EightPoint Ramp motion controller enables smooth, minimized-jerk motion profiles, and simplified trajectory generation. Together with 171-microsteps, 1024-point sine-wave generation, StallGuard™, CoolStep™, and SpreadCycle™, it optimizes motion quality, efficiency, and motor performance.

The device supports control through SPI and STEP/DIR, feedback through an incremental encoder interface, and extensive diagnostic, monitoring, and protection functions.

The TMC3241-EVAL board enables the use of the TMC3241 as part of the ADI Trinamic™ evaluation board system, for example, in combination with the TMCL-IDE, or together with the PyTrinamic™ Python package.
