BOOSTXL-DRV8320x EVM User’s Guide

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.

LED1 and LED2 — During normal motor operations LED1 and LED2 define the direction of spin. When

any fault occurs, LED1 and LED2 flashes in different patterns to identify the fault. Table 1 describes

the patterns observed with different fault conditions.

2.4 Interfacing DRV8320x and MSP430F5529 LaunchPad development kit

The DRV8320x device has 40 pins with different functions. These pins are interfaced with the

MSP430F5529XL LaunchPad development kit which is mapped appropriately to receive the functionality

of the BoosterPack plug-in module plug-in module. These 40 pins are grouped into 4 ports. Table 2 and

Table 3 list the interfacing of these ports with the MSP430F5529 device.

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.

Step 2. Read through and accept the license agreement to proceed with the installation (see

Figure 9).

Figure 9. CCS License Agreement

Step 3. Choose a destination directory. Using the default (c:\ti) removes a step in the SDK installation

procedure (see Figure 10).

Figure 10. Default Installation Location for CCS

Step 4. Choose the processor architectures to install (see Figure 11).

For the DRV83xx, the MSP430 and C28x are the only needed processor packages. The compiler tools

are required. Ensure that the box for the TI MSP430 Compiler Tool is checked.
