1 Introduction
1.1 Overview
The DRV8300 is a gate driver IC for three-phase motor drive applications. It provides three high-accuracy
trimmed and temperature compensated half-bridge drivers, each capable of driving high-side and low-side N-
type MOSFETs.
Along with the hardware of the DRV8300, the
microcontroller-based board has reference
software that sends necessary signals to the DRV8300 to spin a 3-phase Brushless-DC motor. GuiComposer
software allows the user to program settings, enable the motor to spin, and monitor the system from fault
conditions.

1.2 Purpose and Scope
This document is designed to be used as a startup guide to the DRV8300 EVM and LAUNCHXL-F280049C
solution. This document is intended for the engineers involved in the design, implementation, and validation of
D TMS320F280049C reference software.
The scope of this document is to provide the user with a guide to evaluate the DRV8300 device with a
TMS320F280049C isolated board. This document covers the hardware connections required between boards
and external motor/supplies. When the hardware connections are complete, the user is required to download the
necessary tools and software to spin a motor.
The reference software is composed of GuiComposer software with sensored trapazoidal algorithm for BLDC
motor control.
