DRV8316xEVM Evaluation Module
ABSTRACT
This document is provided with the DRV8316xEVM customer evaluation module (EVM) as a supplement to the
DRV8316 data sheet ( DRV8316 4.5-V to 35-V Three-Phase Smart Gate Driver ). This user's guide details the
hardware implementation of the EVM and how to setup and power the board.
Note
The EVM is populated and configured for the DRV8316R (SPI variant) device by default. To configure
the EVM for the DRV8316T (Hardware variant), please see
Section 4.1.1 .
