TMC5130 Slide 8

The BOM shown on this slide is dimensioned for 46 V peak motor supply voltage. When designing for a lower supply voltage, lower voltage capacitors may be used for VM. The given sense resistors are dimensioned for a maximum current of up to 1.4 A (RMS) phase-current, the actual RMS current can be adapted to lower settings by initialization via software. For the best sense resistors to match different motor currents, see the selection guide on the following slide.
