2 Quick Start Guide

The DRV8328AEVM requires a power supply with a recommended operating range from 4.5-V to 60-V. To setup and power the EVM, follow the sequence below:

  1. Connect the power supply ground to the GND of the 2-pin power connector J9 and the power supply positive terminal to the PVDD pin of J9. Ensure jumpers JP1, JP2, and JP3 of the LAUNCHXL-F280049C are not populated (DNP) to ensure that the LaunchPad is powered by the DRV8328AEVM and the motor supply is isolated from the USB.

  2. Connect the motor phases to OUTA, OUTB, and OUTC in the correct order to connector J12. For sensored applications, connect the Hall sensors to the appropriate locations on the 5-pin connector J10 as shown in Figure 3-2. Select AVDD or EXT on jumper J11 to choose the Hall power source voltage.

  3. Mate the DRV8328AEVM onto the top half of the LAUNCHXL-F280049C (LaunchPad Headers J1/J3 and J2/J4) as shown in Figure 3-3. The motor and power connectors should face the same direction as the Micro-USB connector on the LaunchPad.

  4. Remove R26 if toggling nSLEEP from switch on board. Place nSLEEP switch in WAKE position.

  5. Power on the DRV8328AEVM.

  6. Connect a Micro-USB cable from the computer into the Micro USB connector on the top of the LAUNCHXL-F280049C as shown in Figure 3-3.
