The DRV8317HEVM requires a power supply with a recommended operating range from 4.5-V to 20-V. To setup and power the EVM, follow the sequence below:
- Connect the power supply ground to the PGND of the 2-pin power connector J5 and the power supply positive terminal to the VBAT pin of J5. Ensure jumpers JP1, JP2, and JP3 of the LAUNCHXL-F280049C are populated to ensure that 3.3 V and 5 V are powered from the LaunchPad.
- Connect the motor phases to OUTA, OUTB, and OUTC
in the correct order. For sensored applications, connect the Hall sensors to the
appropriate locations on the 5-pin connector J7 as shown in Figure 4-2. Select 3V3
or Ext on jumper J2 to choose the Hall power source voltage to be either from
the 3.3 V on the board or from an external supply.
- Mate the DRV8317HEVM onto the top half of the LAUNCHXL-F280049C (LaunchPad
Headers J1/J3 and J2/J4) as shown in Figure 4-3. Make sure
motor and power connectors face the same direction as the Micro-USB connector on
the LaunchPad.
- Connect a Micro-USB cable from the computer into the Micro USB connector on the top of the LAUNCHXL-F280049C.
- Power on the DRV8317HEVM.
