DRV3204-Q1 EVM

This document is a supplement to the DRV3204-Q1 data sheet (SLVSBT3). It details the hardware

implementation of DRV3204-Q1 evaluation module (EVM). This document does not cover the motor-driver

application and the software.

Section 1 and Section 2 list the hardware descriptions of the EVM. Appendix A details getting started with

the evaluation, and Appendix B describes the 3.3-V interface (I/F) board.

1 Overview

1.1 Introduction

The DRV3204EVM is an application board to evaluate the DRV3204-Q1 device. The DRV3204-Q1 device

is a field effect transistor (FET) pre-driver designed for a 3-phase brushless DC motor control. The EVM

consists of the DRV3204-Q1 device, six N-channel MOSFETs, and passive devices. The DRV3204EVM

has a 5-V level interface to communicate with an external micro-controller unit (MCU). A 3.3-V I/F board is

also provided to support the 3.3-V MCU.
