2 Introduction
is a 3-V to 20-V, 5-A peak integrated three-phase integrated FET driver IC for motor drive
applications. It provides three accurately trimmed and temperature compensated half-bridges capable of directly
driving a 3-phase Brushless-DC motor. The DRV8311 integrates multiple control interface options, low-side
integrated current sense resistors and sense amplifiers, a 3.3-V 100-mA LDO regulator, and a variety of
protection and control features. The device is available in the hardware variant (DRV8311H), SPI variant
(DRV8311S), and Texas Instruments SPI (tSPI) variant (DRV8311P) as shown in

The DRV8311HEVM can be interfaced with the
TMS320F280049C microcontroller
in correspondence with the reference software to provide the algorithm to the DRV8311
to control the BLDC motor.
This document serves as a startup guide to supplement the DRV83 LAUNCHXL-F280049C BLDC
motor control demo kit. It also is intended to help engineers design, implement, and validate reference hardware
and software for the LaunchPad MCU and DRV8311. For step by step details on connecting the LAUNCHXL-
F2 DRV8311HEVM, installing software, and running the project to spin a motor, refer to
