7.4.5 Control Advance Angle
To achieve the best efficiency, the drive state of the motor must be controlled such that the current is aligned with the BEMF voltage of the motor. #SLVSDN21003 illustrates the operation when the drive angle has been optimized. For complete flexibility, the DRV10974 device offers a wide range of fixed lead times. The options for lead time are controlled by a resistor on the ADV pin. The values available are shown in Table 7-4.
