TMC2209-LA
by TRINAMIC
For stepper-driven mechanisms, the TRINAMIC TMC2209-LA provides motor control in a surface-mount IC. The family is known for quiet stepper operation and is used in motion-control applications such as 3D printers. Its QFN package includes an exposed pad, reflected in this record's 29 symbol pins and 29 footprint pads. Available KiCad assets comprise a symbol, the QFN-28_L5.0-W5.0-P0.50-BL-EP footprint and a 3D model for board visualization. The free, verified conversion has seen use by 3 ProtoFlow engineers in real designs. The complete part can be opened directly in ProtoFlow for schematic and PCB work.
