ZHCSHA0C January 2018 – September 2018 DRV10974
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. Figure 17 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 4.
