DRV8311HEVM User's Guide
ABSTRACT
This document is provided with the DRV8311HEVM customer evaluation module (EVM) to evaluate the DRV8311
3-V to 20-V Three-Phase Smart Gate Driver . This User's Guide details the implementation of the EVM and
shows how to set up and power the board with the LAUNCHXL-F280049C (C2000 Piccolo MCU F280049C
LaunchPad™ development kit) .
Note
The DRV8311HEVM comes automatically populated with and configured for the DRV8311H hardware
device. It is also compatible for the DRV8311S and DRV8311P variants, but the user will need to
modify the board to make it compatible for the SPI/tSPI devices (see
Section 4.4 ).
Note
For the DRV8311H Hardware settings to work, R7 must be removed and 3.3 V must be supplied
externally or from the LaunchPad. Please see section DRV8311H Compatability.
