A sense resistor is the most common means of setting the motor current. It provides best precision when using a 1% type, a 5% type will perform fine for most applications. The selection of appropriate sense resistors depends on following considerations. The maximum current to be driven into the motor, use the peak value required. To get more power out of a motor, the user can provide a boost current above the nominal current. Up to 50% more current is realistic for short durations, such as the acceleration phase. The maximum power dissipation resulting from the selection of the resistor. A 0603 resistor is sufficient for a few 100 mA of motor current, higher currents require 0805, 1206, or larger sense resistors to be used (above 1A). During normal run and standstill, most applications allow power reduction to 75%, or even 50%. In case the calculation does not give a well-fitting standard sense resistor value use the next lower value and use the current scaler (CS) parameter for adapting.
