  • Page 3: Introduction

    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.

  • Page 4: Quick Start Guide

    3 Quick Start Guide The DRV8317HEVM requires a power supply with a recommended operating range from 4.5-V to 20-V. To setup and power the EVM, follow the sequence below: 1. Connect the power supply ground to the PGND of the 2-pin power connector J5 and the power supply positive terminal to the VBAT pin of J5.

  • Page 5: Hardware And Software Overview

    4.2 Connection Details Figure 4-2 shows the power supply and motor connections made to the DRV8317HEVM in order to spin a 3-phase sensored or sensorless Brushless-DC motor. A 4.5-V to 20-V power supply or battery is connected to the VBAT and GND terminals. The three phases of the BLDC motor connect directly to the OUTA, OUTB, and OUTC terminals of the screw terminal provided on the DRV8317HEVM.

  • Page 7: Led Lights

    USB cable is plugged in to the LaunchPad. The DRV8317HEVM has 4 status LEDs on the board. By default, the VM and V_BUCK LEDs will light up when the board is powered on. The fault LED will light up when the driver reports a fault, and the MCU LED (tied to GPIO59) can be used for debugging and validation.
