The DRV8329AEVM requires a power supply with a recommended operating range from 4.5-V to 60-V. To setup
and power the EVM, follow the sequence below:
1. Connect the power supply ground to the GND of the 2-pin power connector J10 and the power supply
positive terminal to the PVDD pin of J10. Ensure jumpers JP1, JP2, and JP3 of the LAUNCHXL-F280049C
are not populated (DNP) to ensure that the LaunchPad is powered by the DRV8329AEVM and the motor
supply is isolated from the USB.
2. Connect the motor phases to OUTA, OUTB, and OUTC in the correct order to connector J13. For sensored
applications, connect the Hall sensors to the appropriate locations on the 5-pin connector J11 as shown in
Figure 4-2. Select AVDD or EXT on jumper J11 to choose the Hall power source voltage.
3. Mate the DRV8329AEVM onto the top half of the LAUNCHXL-F280049C (LaunchPad Headers J1/J3 and
J2/J4) as shown in Figure 4-3. The motor and power connectors should face the same direction as the
Micro-USB connector on the LaunchPad.
4. Place nSLEEP switch in WAKE position and DRVOFF in ON position.
5. Power on the DRV8329AEVM.
6. Connect a Micro-USB cable from the computer into the Micro USB connector on the top of the LAUNCHXLF280049C as shown in Figure 4-4.

Hardware and Software Overview
Figure 4-6. User-adjustable jumpers, resistors, and switches on DRV8329AEVM
4.4.1 DRV8329A/B Compatibility
The DRV8329AEVM default is the DRV8329A (Hardware variant), but can also be compatible with the
DRV8329B. The main difference is that DRV8329A operates in 6x PWM mode and DRV8329B operates in
3x PWM mode. To use the DRV8329B, remove the DRV8329A from the EVM and replace with the DRV8329B.
No extra hardware changes are required for 3x PWM operation.
4.5 Interfacing DRV8329AEVM and LAUNCHXL-F280049C LaunchPad
The DRV8329AEVM has 40 pins with different functions. These pins are interfaced with the LAUNCHXLF280049C LaunchPad development kit and are mapped appropriately to receive the functionalities of the
DRV8329 device. These 40 pins are grouped into 4 ports in respect to the LAUNCHXL-F280049C (J1 to J4).

Firmware and GUI Application
6 Firmware and GUI Application
The DRV8329AEVM can implement sensored, sensorless, or Field-oriented control for commutating a 3-phase
Brushless-DC motor. There are two GUIs to support DRV8329A (DRV8329A-EVM-GUI) and DRV8329B
(DRV8329B-EVM-GUI) using sensored trapezoidal commutation with Hall sensor feedback. The GUIs allow
for basic trapezoidal motor control functions such as acceleration, duty cycle control, PWM switching frequency,
MCU dead time insertion, braking, and direction changes. The bus and phase voltage feedback circuits as well
as the integrated CSA provide voltage and current feedback from the motor for over-current and motor voltage
protection.
The following GUIs are available on the Gallery:

6.2 DRV8329x EVM GUI Quick Start Guide
1. Click on the “Output Enable” switch.
2. Enter the PWM frequency in Hz using the “PWM Frequency (Hz)” text box. Press Enter.
3. Adjust the MCU dead time and Acceleration Delay values. You may also use the DT potentiometer to
insert dead time from the DRV8329 rather than the MCU by setting the dead time potentiometer resistance,
enabling the DT_POT jumper, and setting the MCU dead time to 0 ns.
4. To control the motor speed using the speed potentiometer, turn the potentiometer all the way
counterclockwise to set to 0% speed. Click on the “Potentiometer Enable” switch. To not use the
potentiometer to control the motor speed, skip this step.
5. Adjust the “Duty Cycle” slider or enter the duty cycle in the number box to control the speed of the motor
from 0% to 100%.
6. Use the “Direction” switch to switch the direction of the motor.
7. Use the drop-down menu in “Motor Braking” to determine the motor braking type. Click on “Stop Motor” to
stop the method with the selected braking type.
8. If R58 is populated and R11 is not populated, use the nSLEEP switch to put the driver into a low-power sleep
mode.
9. If R69 is populated, use the DRVOFF switch to shut off the gate drivers and Hi-Z the gate driver outputs.
6.3 Using the DRV8329x EVM GUI
The GUI offers the following features:

Firmware and GUI Application
Potentiometer Enable – Enables potentiometer R90 to control the duty cycle of the motor. Duty cycle is
updated in the Duty Cycle slider in real time. Turn all the way clockwise for 0% duty cycle, all the way
counterclockwise for 100% duty cycle.
Direction – Sets direction of the motor. When enabled, motor spins counterclockwise. When disabled, motor
spins clockwise. When the direction is changed, the motor will coast to a stop, wait 1 second, then accelerate
to the duty cycle in the opposite direction.
nSLEEP – Places the DRV8329 in a low-power sleep mode. nSLEEP toggle switch only works when resistor
R26 is populated and resistor R75 is DNP.
DRVOFF – Disables all gate drivers in Hi-Z state.
PWM Frequency – Sets the PWM switching frequency of the motor in Hz.
MCU Dead Time – Sets the MCU deadband time for the PWM inputs in nanoseconds.
Duty Cycle – Sets the duty cycle of the motor when potentiometer is disabled.
Acceleration Delay – Sets the acceleration and deceleration ramp rate in ms per 1% duty cycle.
MOTOR BRAKING SETTINGS
•
Stop Motor – Stops the motor when toggled according to the braking method in the drop-down menu. The
two methods are brake (turn on all low-side MOSFETs) and coast (float all MOSFETs).
CSA SETTINGS
•
•
•
Over-current Limit – Sets the overcurrent limit in amps. If ISEN is measured to be over the overcurrent limit,
Over-Current fault is triggered.
Current Sense Resistor – Sets the resistor value in ohms for the shunt resistor onboard the EVM. Default
resistor populated is 0.001 ohm.
CSA Gain – Gain of the integrated CSA on the EVM. Set the CSA gain setting to match the CSAGAIN setting
on J2 of the EVM so the firmware can calculate the ISEN current correctly.
FAULT STATUS BITS
•
•
•
•
•
Fault Status – Logical “or” of all faults. When a fault occurs, Output Enable is turned off, Duty Cycle is set to
0%, and the corresponding fault status LED is lit.
PVDD Overvoltage Fault – PVDD is over 60 V. Configurable through firmware.
PVDD Undervoltage Fault – PVDD is under 4.5 V. Configurable through firmware.
Over-Current – Measured LSS current is over the Over-Current threshold.
DRV8329 Fault – Fault indicated by the DRV8329. See DRV8329 datasheet.
