Introduction
1.1
Device Overview
www.ti.com
The DRV835x 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 lowside 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 DRV8350x, the MSP430F5529 microcontroller has loaded reference software
that provides the necessary gating pulses to DRV8350x to control the BLDC motors.
Figure 2. Block Diagram
1.2
Purpose and Scope
This document is designed to be used as a startup guide and to supplement the DRV835X +
MSP430F5529 BLDC motor control demo code kit. This document is intended for the engineers involved
in the design, implementation, and validation of DRV835X + MSP430F5529 reference software.
The scope of this document is to provide the user with a guide to evaluate the DRV8350x device with an
MSP430F5529 development environment. This document covers the hardware connections required to
power the DRV8350x-EVM, to drive the motor sensorless or sensored, and to interface to the PC. 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
DRV8350x 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 DRV835xx EVM Sensored Software User's Guide
and DRV835xx EVM Sensorless Software User's Guide.

Hardware Overview
2.1
Hardware Connections Overview – DRV8350x + MSP430F5529
Figure 3 shows the major blocks of the DRV8350x-EVM hardware. The DRV8350x-EVM is designed for
an input supply from 12 to 95 V and up to 15-A RMS 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 digital supplies are
derived from the LP2992 LDOs that output 3.3 V and 5 V. The hall sensor power can be selected from
these two power lines.

Connection Details
The image above shows the power connector and motor phase connector. A supply voltage ranging from
6 to 95 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 DRV8350x-EVM.
The image below shows where the Micro-USB cable is plugged in to power the EVM and provides
communication between the MSP430F5529 firmware and GUI. Also, you can see the emulation
environment of the EVM.

Below is a clearer view of the MSP430F5529 MCU. The component D3 is an LED that indicates if the
firmware is running on this target MCU. Press the reset button whenever you wish to reset the firmware
loaded on this target MCU
Figure 5. MSP430F5529
Each device variant has different sets of resistors required for S variant or H variant. See the schematic in
the Hardware Design Files for more information.
The image below exhibits the 12 V buck converter, LM50008A, that powers the DRV8350x IC in split rail
configuration. The U6 component is a LP2992 LDO that converts the 12 V into a 5 V output for the digital
environment. Finally, the U7 component is a LP2992 LDO that converts the 5 V and drops it down to 3.3 V
for the digial environment and for the driver pull up resistor power.

Figure 6. Power Environment for EVM
The DRV8350x-EVM GUI has a resistor divider tied to an ADC channel of the MSP430F5529 (pin 6.4).
The bottom resistor varies in value between 2.0 k and 4.0 k to vary the ADC input voltage. The firmware
reads this voltage and interprets what device is connected. Thus, the correct device is identified in the
GUI.

Interfacing DRV8350x and MSP430F5529
The DRV8350x device interfaces with the MSP430F5529 through a number of device to device pins. To
find out more about what pin is which, proceed to look at the schematic. Below you can get a functional
overview of the pin connections.

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 21).
Step 3. Click the OK button to accept.

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 29
and Figure 30 show the update process.

The hardware required to run the motor control is the MSP430F5529, the DRV8350x-EVM , a Micro-USB
cable, and a power supply with a DC output from 12 to 95 V. Follow these steps to start up the module:
Step 1. Connect the three phases from the brushless DC motor to the Motor connector on the
DRV8350x-EVM. MOTA, MOTB, and MOTC are labeled in white silkscreen on the PCB top
layer.
NOTE: If using the sensored firmware on the MSP430F5529, connect a brushless DC motor Hall
sensor inputs to hall sensor header and solder the unpopulated R82, R84, and R86 0 ohm
resistors. If using sensorless firmware, this header can be left unconnected.
NOTE: If using 1x PWM Mode with the sensored firmware the hall sensor 0 ohm resistors must be
populated.
Step 2.
Connect the DC power supply to the power connector.
NOTE: Observe the correct polarity of +VM and GND connections on the DRV8350x-EVM
connection
Step 3.
Step 4.
4.3
Connect a Micro-USB cable to the EVM's USB port.
Turn on the power supply and power up the PCB.
Launching DRV835X-EVM EVM GUI
The DRV8350X-EVM GUI works with the two different DRV8350x-EVM to facilitate control of brushless
DC motors. The DRV8350X-EVM GUI provides functionality for adjusting the speed and direction of the
motor, setting various fault parameters such as voltage and current protection limits, observing the motor
drive speed, and monitoring the device fault status. The GUI can also be used to tune the motor for best
performance using various parameters available in the motor control parameter page.
To launch the GUI, click on the DRV8350X-EVM EVM shortcut on the desktop or navigate to the Windows
Start Menu and click All Programs. Navigate to the Texas Instruments folder and select the DRV8350XEVM folder.
The Device Launch page is displayed to launch one of the 2 device variants (DRV8350S, DRV8350H).
Click on one of the Launch buttons to launch next either the DRV8350S or DRV8350H labels.
For a guide on the different attributes of the DRV8350X-EVM EVM GUI, refer to the DRV835X-EVM GUI
