3 Quick Start Guide

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:

  1. 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.
  2. 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.
  3. 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.
  4. Connect a Micro-USB cable from the computer into the Micro USB connector on the top of the LAUNCHXL-F280049C.
  5. Power on the DRV8317HEVM.
