    Hello,

    If you wish to increase the peak drive current of the gate drivers, then you have to adjust the IDRIVE Pin resistor (configuration settings can be found in Table 5 of the datasheet).

    If you wish to increase the maximum current through the motor windings, then you have to adjust Rsense and Vref (Equation 1 on the datasheet)\
