  • Page 5: Quick Start Guide

    Quick Start Guide 3 Quick Start Guide The DRV8311HEVM requires a power supply with a recommended operating range from 3-V to 20-V. To setup and power the EVM, follow the sequence below: 1. Connect the power supply ground to the GND of the 2-pin power connector J3 and the power supply positive terminal to the VM pin of J3.

  • Page 6: Hardware And Software Overview

    4.2 Connection Details Figure 4-2 shows the power supply and motor connections made to the DRV8311HEVM in order to spin a 3-phase sensored or sensorless Brushless-DC motor. A 3-V to 20-V power supply or battery is connected to the VM 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 DRV8311HEVM.

  • Page 8: Led Lights

    USB cable is plugged in to the LaunchPad. The DRV8311HEVM has 4 status LEDs on the board. By default, the VM and 3V3 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.

User-selectable jumpers and DNP components on DRV8311HEVM 4.4.1 DRV8311H Compatibility The DRV8311HEVM default is the DRV8311H (Hardware variant), which can be used to spin a 3-phase Brushless-DC motor with selectable modes configured with hardware settings as shown in Table 4-3.
  • Page 12 The DRV8311HEVM is compatible with the DRV8311P (tSPI variant) to spin a 3-phase Brushless-DC motor using enhanced Texas Instruments SPI (tSPI). tSPI is a protocol that allows for multiple motor drivers to be controlled via one SPI bus. Each device has a selectable address in hardware and tSPI protocol allows for individual control of each driver through SPI communication from a single microcontroller unit (MCU).
  • Page 13 Hardware and Software Overview 4.4.5 Interfacing DRV8311HEVM and LAUNCHXL-F280049C LaunchPad The DRV8311HEVM has 40 pins with different functions. These pins are interfaced with the LAUNCHXLF280049C LaunchPad development kit and are mapped appropriately to receive the functionalities of the DRV8311H device. These 40 pins are grouped into 4 ports in respect to the LAUNCHXL-F280049C (J1 to J4).
