1 Introduction
1.1 Device Overview
The DRV8320x is a gate driver IC for three phase motor drive applications. It provides three high-accuracy
trimmed and temperature compensated half bridge drivers, each capable of driving a high-side and low-
side N-type MOSFET.
Both SPI and hardware interface variants provide detailed fault reporting and flexible parameter settings
such as current control options for slew rate control of the gate drivers and various protection features.
Along with the hardware of DRV8320x, the MSP430F5529 microcontroller has loaded reference software
that provides the necessary gating pulses to DRV8320x to control the BLDC motors.
Figure 1. Block Diagram
1.2 Purpose and Scope
This document is designed to be used as a startup guide and to supplement the DRV832X +
MSP430F5529 BLDC motor control demo code kit. This document is intended for the engineers involved
in the design, implementation, and validation of DRV832X + MSP430F5529 reference software.
The scope of this document is to provide the user with a guide to evaluate the DRV8320x device with an
MSP430F5529 LaunchPad™ development kit. This document covers the hardware connections required
between DRV8320x and the LaunchPad development kit. When the HW connections are complete, the
user is required to download the necessary tools and SW to spin a motor. For step-by-step details to instal
the Code Composer Studio™ (CCS) software, import the DRV832xx project into CCS, build the project,
debug the project, and spin the motor, refer to Section 3.
This reference SW comprises trapezoidal sensored and sensorless algorithms for BLDC motor control.
For additional information on these algorithms, refer to DRV832XX EVM Sensored Software User's Guide
and DRV832XX EVM Sensorless Software User's Guide.

2 Hardware Overview
2.1 Hardware Connections Overview – DRV8320x + MSP430F5529
Figure 2 shows the major blocks of the hardware where the BOOSTXL-DRV8320x BoosterPack™ plug-in
module is mounted on the MSP430F5529XL LaunchPad development kit. The BOOSTXL-DRV8320x is
designed for an input supply from 6 to 54 V and up to 15-A drive current. Three half h-bridges capable of
driving a three-phase BLDC motor implementing sensored or sensorless control. Hall sensor pins a, b, c
are connected to pins P2.0, P2.2, and P2.6 of the MSP430™ MCU, respectively. The 3.3-V supply to the
Hall sensors is derived by the LMR16006XDDCR buck converter integrated in the DRV8320x.

2.2 Connection Details
Figure 3 shows the power connector and motor phase connector. A supply voltage ranging from 6 to 54 V
from a battery or a DC voltage source is connected to the voltage supply pins. Three phases of the BLDC
motor are connected to the three-phase motor socket provided on the BOOSTXL-DRV8320x.

2.3 LED Lights and Switch Functions
Two LEDs and two push-button switches are available on the MSP430F5529 LaunchPad development kit
to notify the user of different motor statuses and to control the operation of the motor. These switches are
configured in the reference software and preloaded with the following functions:
Figure 7. Switches and LED Functions
P1.1 switch (motor direction reversal) — This switch allows the user to toggle the direction of motor
spin either to be clockwise or counterclockwise rotation.
P2.1 switch (fault clear switch) — This switch is configured to clear the fault status in SPI registers and
to restart the motor. When the user does not want automatic fault recovery when a fault occurs, it
can be turned off in the parameter setup file. In such cases, this button helps in restarting motor
after successful identification and mitigation of fault.

3 Firmware Installation
3.1 Installing Code Composer Studio
CCS versions 5.x.x and 6.x.x have been used and tested for DRV832XX reference code. An authorized
version can be installed from www.ti.com/tool/ccstudio.
NOTE: A myTI login account is required to download CCS as well as the SDK package. This section
describes the installation procedure for CCS5.4; however, installing other versions of CCS
v5.x including CCS v6.x is similar.
After following the required steps to download the CCS installer, the ccs_setup_5.4.0.00091.exe file
should be located in the specified download directory. Figure 8 shows this file.
Figure 8. Downloaded Executable for Code Composer Studio Installation
Follow the installation process listed:
Step 1. Run the installer by double clicking the ccs_setup_win32.exe file.

3.3 Creating or Importing a DRV8x Project into CCS
When the CCS software is started, the user must first select a workspace. A workspace is the structure in
which projects are kept. Multiple projects can be saved in one workspace. TI recommends starting with
the project for the specific DRV8x device. After importing an existing project, the user can explore the
features of CCS to become familiar with the IDE. Follow these steps to import the provided project:
Step 1. Double click the CCS icon to open the application. A CCS icon is placed on the desktop after
installation.
Step 2. Select the location and name of the workspace. The location and naming convention can be
changed based on the user's preference (see Figure 22).
Step 3. Click the OK button to accept.
Figure 22. Workspace Launcher
After selecting the workspace, the CCS software opens displaying a welcome menu.
Step 4. Import a project either from the welcome menu by selecting Import Project or go to the
Project menu and select Import Existing CCS Eclipse Project (see Figure 23).
Figure 23. Importing Existing Projects
Step 5. In the new window that appears showing the import options, click the Browse... button and
find the provided projects through the folder browser. These projects are located in the SDK
installation directory. The example location is C:\ti\DRV832XX-V1.0 (see Figure 24). When
selected, the provided project appears under Discovered Projects.
Step 6. Make sure the correct box is checked and then click the Finish button (see Figure 24.

3.4 Updating the MSP430 USB-FET
After the reference project is imported and selected in the CCS software, the provided software builds and
runs on the MSP430 device. The device is programmed by the MSP430 USB-FET. When this device is
used, the CCS software automatically detects the firmware version and notifies of an update. The process
takes a few minutes, let the update complete before unplugging the USB cable or closing CCS. Figure 30
and Figure 31 show the update process.
CAUTION
To help prevent any device damage, wait for the update to finish before
unplugging the MSP430 device or closing CCS.
