The given BOM is dimensioned for 48V peak motor supply voltage, while offering a tiny footprint. It is realized on the TMC6200-BOB breakout board. It uses compact dual MOSFETs and dual 1206 sense resistors. The resulting value of 16 mΩ is designed for a maximum current of up to 10ARMS phase current at 5 times amplification. 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 calculation formula.
