4.4.1 DRV8329A/B Compatibility
The DRV8329AEVM default is the DRV8329A (Hardware variant), but can also be compatible with the
DRV8329B. The main difference is that DRV8329A operates in 6x PWM mode and DRV8329B operates in
3x PWM mode. To use the DRV8329B, remove the DRV8329A from the EVM and replace with the DRV8329B.
No extra hardware changes are required for 3x PWM operation.
4.5 Interfacing DRV8329AEVM and LAUNCHXL-F280049C LaunchPad
The DRV8329AEVM has 40 pins with different functions. These pins are interfaced with the LAUNCHXL-
F280049C LaunchPad development kit and are mapped appropriately to receive the functionalities of the
DRV8329 device. These 40 pins are grouped into 4 ports in respect to the LAUNCHXL-F280049C (J1 to J4).
Table 4-3
and
Table 4-4
list the interfacing of these ports of the DRV8329AEVM headers J3 and J4.
