Connecting the Hardware

Use the following steps to connect the hardware:
1. Plug the BOOSTXL-DRV8305EVM BoosterPack onto the LaunchPad as shown in
terminal block headers should be oriented towards the USB connector and the 20-pin headers (J1 and
J2) should align properly.
2. Connect the 3-phase motor to the terminal block header J4. The motor connections have been labeled
with A, B, and C but can be connected in any order.
3. Connect the power supply, that will power the BoosterPack's DRV8305 3-phase gate driver, 3-phase
power stage, and LMR16006 buck regulator to the terminal block header J3. The connections have
been labeled PVDD and GND. For full performance, ensure the supply can support as much current as
your motor may demand. The BoosterPack has a designed operating range from 4.4- to 45-V with up
to 15-A RMS (20-A peak) of phase output current.
At high currents the drive stage can increase to high temperatures.
Use proper handling procedures.
4. Enable the power supply. A fault may appear on the nFAULT LED. This is normal and should be
cleared when the status registers are read or EN_GATE is taken HIGH.
5. Enable the control algorithm and begin spinning the motor. The BOOSTXL-DRV8305EVM
BoosterPack combined with a compatible XL LaunchPad will provide a complete motor drive and
control evaluation platform. With the Piccolo LAUNCHXL-F28027F LaunchPad you can take full
advantage of TI's InstaSPIN™-FOC sensorless control solution. To get started with InstaSPIN-FOC
(http://www.ti.com/instaspin-foc) download and run the MotorWare™ software
(http://www.ti.com/tool/motorware), reviewing the LAUNCHXL and BOOSTXL resources.
