2 Introduction
The DRV8316 is an 4.5-V to 40-V, 8-A peak integrated three-phase gate driver IC for motor drive applications.
It provides three accurately trimmed and temperature compensated half-bridges capable of directly driving a
three-phase brushless-DC motor. Both the SPI variant (DRV8316R) and hardware interface variant (DRV8316T)
integrates an adjustable buck regulator, flexible parameter settings such slew rate control, and protection
features, and both are compatible with the DRV8316xEVM. See Table 2-1.
Table 2-1. DRV8316 variants
Device Name Variant
DRV8316R Buck regulator and SPI
DRV8316T Buck regulator and Hardware
Along with the hardware of the DRV8316xEVM, the TMS320F280049C microcontroller on the LAUNCHXL-
F280049C LaunchPadTM has reference software that provides the algorithm to the DRV8316 to control the
BLDC motor.
This document serves as a startup guide to supplement the DRV8316xEVM + LAUNCHXL-F280049C BLDC
motor control demonstration kit. It also is intended for engineers to design, implement, and validate reference
hardware and software for the LaunchPad™ MCU and DRV8316R. For step-by-step details on connecting the
LAUNCHXL-F280049C + DRV8316xEVM, installing software, and running the project to spin a motor, refer to
Section 5 Hardware Setup.

3 Quick Start Guide
The DRV8316xEVM requires a power-supply source, which has a recommended operating range from 4.5 V to
35 V. To setup and power the EVM, use the following sequence:
1. Connect the power supply ground to PGND of the two-pin power connector J5 and the voltage pin to
the VBAT pin. Ensure R13 on the bottom layer is not populated and that jumpers J1-J3 of the LAUNCHXL-
F280049C are populated (USB powers LaunchPad).
2. Connect the motor phases to OUTA, OUTB, and OUTC. If using the Hall sensors, connect them to five-pin
connector J7 as Figure 4-6 shows. Select 3.3 V or HALL_EXT_PWR on jumper J8 to select Hall power
source.
3. Mate the DRV8316xEVM onto the top half of the LAUNCHXL-F280049C (Launchpad Headers J1/J3 and
J2/J4) as Figure 4-7 shows. The motor and power connectors should face the same direction as the
Micro-USB connector on the LaunchPad.
4. Power on the DRV8316xEVM.
5. Connect a Micro-USB cable from the computer into the Micro USB connector on the top of the LAUNCHXL-
F280049C.

4 Hardware and Software Overview
4.1 LEDs, Switches, and Jumpers
There are LED indicators on both the LAUNCHXL-F280049C and DRV8316xEVM when power is provided.
The LAUNCHXL-F280049 LaunchPad LEDs power up when the Micro-USB cable is plugged in and their
functionalities are not modified upon powering the board.
The DRV8316xEVM has four status LEDs implemented on the board. By default, the VM and 3.3-VBK LEDs
will light up when the board is powered and the MCU LED (tied to GPIO59) can be used for debugging and
validation. Table 4-3 shows LED descriptions including those that are on during power up in bold and Figure 4-1
shows the locations of the LEDs.

4.1.1 DRV8316T Compatibility
The DRV8316xEVM is compatible with the DRV8316T (H/W variant) as the featured motor driver IC to spin
a three-phase Brushless-DC motor. The DRV8316T replaces the SPI settings with five specific pin settings
(MODE, SLEW, OCP/SR, GAIN, and VSEL_BK) that can be adjusted through resistor dividers.
When using the DRV8316T, the SPI enable resistors in the “Depop. if DRV8316T” silk screen box are to be
depopulated (R9-R12) and the resistor dividers in the “Hardware Variant Resistors” silk screen box are to be
populated (R37-R46) with the desired settings. Figure 4-4 shows this setup.
Table 4-3 shows the status of populated and DNP resistors for the two compatible DRV8316x variants. Table 4-4
shows the user-adjustable resistor divider settings when using the DRV8316T. R37-R41 resistors tie to AVDD
and R42-R46 tie to AGND. The defaults of the two tables are in bold.

Figure 4-5 shows the major blocks of DRV8316xEVM plugin module that mounts to the J1/J3 and J2/J4 headers
of the LAUNCHXL-F280049C LaunchPad development kit. The DRV8316xEVM is designed for an input supply
from 4.5-V to 35-V and up to 8-A drive current. The DRV8316 includes three integrated half-bridges that can
drive 8-A peak current and can be used in systems implementing sensored, sensorless, or field-oriented control.
The 3.3-V supply to the Hall sensors is derived by the buck converter integrated in the DRV8316.

5 Hardware Setup
The hardware required to run the motor control is the LAUNCHXL-F280049C LaunchPad development kit, the
DRV8316xEVM, a Micro-USB cable, and a power supply with a DC output from 8-V to 32-V. Follow these steps
to start up the DRV8316xEVM:
1. Mate the DRV8316xEVM board to the top half of the LAUNCHXL-F280049C LaunchPad development kit
(mates to J1/J3 and J2/J4 of the LaunchPad, as in Figure 4-7). Ensure resistor R13 is DNP on the bottom of
board to separate buck voltage from the USB power supply voltage.
2. Connect the three phases from the brushless DC motor to the three-pin connector J4 on DRV8316xEVM.
Phases OUTA, OUTB, and OUTC are labeled in white silkscreen on the PCB top layer. If using a sensored
algorithm on the LaunchPad development kit, connect the Hall sensor to the five-pin connector J7.
3. Connect the DC power supply to header J5, ensuring the correct polarity of VBAT and PGND is applied.
4. Connect a Micro-USB cable to the LaunchPad development kit and computer.
5. Turn on the power supply and power up the PCB.
6. If using the DRV8316xEVM with an external microcontroller, make the logic-level connections needed on
the male headers on the top of the board or female connectors on the bottom side of the board. The signal
names are labeled on the bottom side of the board for convenience as Figure 5-1 shows.

6 Firmware and GUI Application
The DRV8316xEVM can implement sensored, sensorless, or Field-oriented control for commutating a three-
phase Brushless-DC motor. The supported firmware is a sensorless ield-oriented control algorithm adapted from
Texas Instruments’ MotorControl SDK Library of motor solutions. The algorithm includes motor identification and
parameters, sensorless sinusoidal commutation, torque and speed control, and field weakening to maximize
the performance of the motor. The firmware uses GUI Composer to run the algorithm and includes a tab to
read/write to the DRV8316 SPI registers.
The following steps describe how to identify useful motor parameters, spin the motor using a sensorless
sinusoidal profile, use the PI controller gain settings for torque and speed control, and communicate with the
DRV8316 SPI registers. For more information on advanced features of the C2000 InstaSPIN Universal GUI such
as MTPA or Field-weakening , consult the MotorControl SDK InstaSPIN Lab Guide (in the MotorControl Software
Development Kit tool page) and InstaSPIN-FOC and InstaSPIN-MOTION User’s Guide.
6.1 C2000™ InstaSPIN™ Universal GUI
1. Follow the instructions in Section 5 Hardware Setup and ensure the LAUNCHXL-F280049C is connected to
the PC and the power supply is turned on to the DRV8316xEVM PCB.
2. Access the GUI Composer Gallery https://dev.ti.com/gallery/ and search for
"DRV8316xEVM_InstaSPIN_Universal_GUI". Click on the GUI.
3. Accept the readme as shown in Figure 6-1 and check the bottom left hand corner of the screen for
“Hardware Connected”. Once connected, the GUI will flash the algorithm to the MCU as shown in Figure 6-2.

6.2 Motor Identification
1. Check the “Enable System” box to enable the InstaSPIN algorithm and run preset calibrations. When the
preset calibrations are finished, the "OffsetCalc" checkbox will automatically uncheck itself.
2. If using the DRV8316R, click on the DRV8316 SPI tab. Click "Read" to read the defaults of the DRV8316R
device. Ensure the CSA_GAIN setting (Control Register 5) reads CSA_Gain_0p15. This setting ensures that
the CSA current output when identifying the motor does not saturate, or else it will incorrectly identify the
motor parameters and limit the maximum performance.
3. Alternatively, if using the DRV8316T, set the GAIN setting to 0.15 V/A by placing a 0-ohm resistor at R44
(in the Hardware Variant Resistors box). This setting ensures that the CSA current output when identifying
the motor does not saturate, or else it will incorrectly identify the motor parameters and limit the maximum
performance.
4. Check the “Run” box to begin the motor identification algorithm. The motor will begin to spin and stop as
it goes through many states to calculate and identify useful motor parameters for sensorless Field-oriented
control. This should take no more than a couple of minutes.
5. Once the motor identification process is complete, the “Motor Identified” indicator will light up, the “Run” box
will be automatically unchecked, and the values Rs, Rs Online, Ls-d, Ls-q, Flux, and Rr will update for that
motor as shown in Figure 6-3. These values will be automatically used for sensorless Field-oriented control.
