3.4.1 DRV8328A/B Compatibility

The DRV8328AEVM default is the DRV8328A (Hardware variant), but can also be compatible with the DRV8328B. The main difference is that DRV8328A operates in 6x PWM mode and DRV8328B operates in 3x PWM mode. Figure 3-7 shows the default resistors to select the A/B variant when the DRV8328A or DRV8328B is used. Ensure resistors R1-R10 are removed, C1 is removed, and resistors R11-R21 are populated (except R16).

Table 3-3 shows the resistors to be only populated as well as their pin and functions.
