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 TMS320F280049C 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.

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 DRV8300 + 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.
