2 Introduction

The DRV8317 is a 4.5-V to 20-V, 5-A peak integrated three-phase FET driver IC for motor drive applications. It provides three integrated half-bridges capable of directly driving a 3-phase Brushless-DC motor. The DRV8317 integrates multiple control interface options, low-side integrated current sense resistors and sense amplifiers, a 3.3-V 80-mA LDO regulator, and a variety of protection and control features. The device is available in the hardware variant (DRV8317H) and SPI variant (DRV8317S) Table 2-1.

The DRV8317HEVM can be interfaced with the TMS320F280049C microcontroller on the LAUNCHXL-F280049C LaunchPad in correspondence with the reference software to provide the algorithm to the DRV8317 to control the BLDC motor.

This document serves as a startup guide for the DRV8317HEVM + 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 DRV8317. For step by step details on connecting the LAUNCHXL-F280049C + DRV8317HEVM, installing software, and running the project to spin a motor, refer to Section 5.
