DRV8833C Evaluation Module

This document is provided with the DRV8833C customer evaluation module (EVM) as a supplement to the
DRV8833C datasheet (

SLVSCP9

). The user's guide details the hardware implementation of the EVM.

Throughout this user's guide, the abbreviation

EVM

and the term

evaluation module

are synonymous with

the DRV8833CEVM, unless noted otherwise.
