Motor Drive BoosterPack Quick
Start Guide: BOOSTXL-DRV8301
Meet the Motor Drive BoosterPack based on the DRV8301
3-Phase Pre-Driver and CSD18533Q5A N-Channel
NexFETTM Power MOSFETs. This BoosterPack provides a
complete 3-phase drive stage in order to evaluate your
motor applications!
1. BoosterPack Features
• Complete 3-phase drive stage in a small form factor
(2.2” x 2.3”)
• Supports 6-24 V and up to 10 A RMS (14 A Peak)
• 6x CSD18533Q5A N-Channel NexFET Power MOSFETs
(< 6.5 mΩ)
• Individual phase and DC bus voltage sense
• Low side current shunt sense on each phase
• Fully protected drive stage including short circuit, thermal,
shoot-through, and under voltage protection
• Integrated 1.5 A step down buck converter
• Combine with compatible LaunchPad XL kits to create a
complete 3-phase motor drive control platform
• Optimized for the Piccolo LAUNCHXL-F28027F

2. BoosterPack Pinout
The BOOSTXL-DRV8301 brings out a
mixture of power, control, and feedback
signals to the LaunchPad XL headers.
• DRV8301’s onboard step down buck
converter provides 3.3 V power to the
LaunchPad
• Fault reporting through the nFAULT and
nOCTW signals

3. Getting Started With Your BoosterPack
The Motor Drive BoosterPack is not a standalone evaluation kit and requires a compatible LaunchPad XL to provide the
appropriate control signals. In addition to the Motor Drive BoosterPack and a compatible LaunchPad XL, you will require a
3-phase motor and sufficient power supply.
I.
Since the DRV8301 has an on board step down buck converter the Motor Drive BoosterPack has been designed to provide
system power for the LaunchPad. Remove the appropriate jumper (JP1 OUT on LAUNCHXL-F28027F) on the LaunchPad
to disconnect the controller and emulation power supplies. You also need to disconnect the controller and emulation
UART through either the appropriate switch (S4 to OFF on LAUNCHXL-F28027F) or jumpers to ensure proper nFAULT and
nOCTW reporting.
II. Plug the Motor Drive BoosterPack onto the LaunchPad as shown in Figure 1. The terminal block headers should be
oriented towards the USB connector.
III. Connect your Three Phase motor to the terminal block header J11. The motor connections have been labeled with A, B,
and C but can be connected in any order.
IV. Connect your power supply, that will power the Motor Drive BoosterPack’s DRV8301 3-Phase Pre-Driver and Drive Stage,
to the terminal block header J2. The connections have been labeled PVDD and GND. For full performance ensure you can
supply as much current as your motor may demand. The Motor Drive BoosterPack has a designed operating range from
6-24 V up to 10 A RMS (14 A Peak)*.
V.
Enable your power supply.
VI. Enable your control algorithm and spin that motor! The BOOSTXL-DRV8301 BoosterPack combined with a compatible
LaunchPad XL will provide a complete motor drive and control evaluation platform. With the Piccolo LAUNCHXL-F28027F
LaunchPad you can take full advantage of TI’s InstaSPINTM-FOC sensorless control solution. To get started with

LAUNCHXL and BOOSTXL resources.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
