3.4.2 DRV8328C/D Compatibility
The DRV8328AEVM is also compatible with the DRV8328C and DRV8328D variants to spin a 3-phase
Brushless-DC motor but requires modifications to the EVM. The main modifications are removing and populating
the correct 0-ohm resistors so pins of the DRV8328C/D variants are properly configured for their functions.
The DRV8328C and DRV8328D device remove the VDSLVL and dead time pins and are replaced with a
DRVOFF shutdown pin and LDO (AVDD). The main difference between the two devices are that DRV8328C
operates in 6x PWM mode and DRV8328D operates in 3x PWM mode.
shows the default components to select the C/D variant when the DRV8328C or DRV8328D is used.
Ensure resistors R11-R21 are removed, resistors R1-R10 are populated, and C1 is populated. You can use the
spare capacitor C45 to populate to C1.
It is also good to remove J8 and J16 to prevent AVDD from back-powering into the external LDO since AVDD
comes from the DRV8328C/D.
