2 Introduction
The DRV8316 is a 4.5-V to 32-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 DRV8316REVM.
Along with the hardware of the DRV8316REVM, 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 DRV8316REVM + 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 + DRV8316REVM, installing software, and running the project to spin a motor, refer to
Section 5 Hardware Setup.

3 Quick Start Guide
The DRV8316REVM 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 4-2 shows. Select 3.3V or HALL_EXT_PWR on jumper J8 to select Hall power
source.
3. Mate the DRV8316REVM onto the top half of the LAUNCHXL-F280049C (Launchpad Headers J1/J3 and
J2/J4) as Figure 4-3 shows. The motor and power connectors should face the same direction as the Micro-
USB connector on the LaunchPad.
4. Power on the DRV8316REVM.
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 Hardware Connections Overview – DRV8316REVM + LAUNCHXL-F280049C
Figure 4-1 shows the major blocks of DRV8316REVM plugin module that mounts to the J1/J3 and J2/J4 headers
of the LAUNCHXL-F280049C LaunchPad development kit. The DRV8316REVM is designed for an input supply
from 4.5 V to 32 V and up to 15-A drive current. The DRV8316R 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 DRV8316R.
Figure 4-1. Major DRV8316REVM Hardware Blocks
4.2 Connection Details
Figure 4-2 shows the connections made to the DRV8316REVM to spin a three-phase sensored Brushless-DC
motor.
An 8-V to 32-V power supply or battery is connected to the VBAT and PGND terminals. There is a reverse
polarity protection implemented on the VBAT and PGND terminals. To bypass the reverse polarity protection and
pi filter implementation, R20 can be populated on the bottom of the board.
The three phases of the BLDC motor connect directly to the OUTA, OUTB, and OUTC terminals of the screw
terminal provided on the DRV8316REVM.

4.3.1 DRV8316T Compatibility
The DRV8316REVM 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 4-7 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.

5 Hardware Setup
The hardware required to run the motor control is the LAUNCHXL-F280049C LaunchPad development kit, the
DRV8316REVM, 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 DRV8316REVM:
1. Mate the DRV8316REVM 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 4-3). 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 DRV8316REVM.
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 DRV8316REVM 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 DRV8316REVM 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 DRV8316REVM PCB.
2. Access the GUI Composer Gallery https://dev.ti.com/gallery/ and search for
"DRV8316REVM_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.
2. 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.
3. 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 Field-oriented control modulation
techniques such as MTPA, Field-weakening, and PowerWarp (EPL).

6.3 Sensorless Sinusoidal Commutation
1. To spin the motor freely with a sinusoidal current profile, check the “Run” box again. The motor will spin with
sinusoidal current at the speedRef (Hz) value in the GUI, which is automatically set to 20.0 Hz. Use the
speedRef (Hz) input to change the current speed of the motor as shown in Figure 6-4.
2. Use the input acceleration Max (Hz/s) to adjust the rate at which the motor will change speed (when
speedRef (Hz) is changed).

6.4 Torque and Speed Control
1. The MotorControl SDK InstaSPIN Lab Guide contains detailed lab overviews of how to use the provided PI
controller to tune the Kp and Ki values for dynamic torque and speed control based on the mechanical
system of the motor when running. Lab 6 (is06_torque_control) describes how to tune the Kp and Ki gains for
dynamic torque control, and Lab 7 (is07_speed_control) describes a similar process for dynamic speed
control.
2. To adjust the gains and currents for the direct and quadrature domains, adjust the Kp_spd, Ki_spd, Id_Kp,
Id_Ki, Iq_Kp, and Iq_Ki constants accordingly based on system specifications as Figure 6-5 shows. The
algorithm will automatically estimate these values initially based on maximum current and motor inertia
settings in “user.h” of the InstaSPIN firmware.
