DRV824x_DRV814x-Q1EVM User's Guide ABSTRACT This document is provided with the DRV824x-Q1EVM and DRV814x-Q1EVM customer evaluation module (EVM) as a supplement to the Automotive DRV824x-Q1 and DRV814x-Q1 Motor Driver data sheets. This user's guide details the hardware implementation of the EVM and how to install the software packages. -
Page 2: Introduction
This document is designed to be used as a startup guide and to supplement the DRV824x-Q1EVM and DRV814x-Q1EVM (“EVM”). The scope of this document is to provide the user with a guide to evaluate the DRV824x-Q1 and/ or DRV814x-Q1 device using a Graphical User Interface (GUI). The GUI application is required to control the EVM. -
Page 3: Evaluation Hardware Overview
2.2 Connection Details Table 2-1 for a brief comparison of both the DRV824x-Q1EVM and DRV814x-Q1EVM in the VQFN HotRod™ package. The 28-pin leaded package (HVSSOP or HTSSOP) version of EVM leverages much of the same design and is also covered by this document. From a firmware and GUI perspective, the two package options are interchangeable. - Page 4 Evaluation Hardware Overview www.ti.com Table 2-1. DRV814x-Q1EVM and DRV824x-Q1EVM Comparison DRV814x-Q1EVM DRV824x-Q1EVM • H-bridge/ dual independent half-bridge outputs in VQFN • Single half-bridge output in VQFN HotRod™ package HotRod™ package • SPI and Hardware control variants • SPI and Hardware control variants...
- Page 5 2.2.1 Common Connectors and Headers Across all EVM Variants Figure 2-1 shows a larger view of the DRV824x-Q1EVM. Because the DRV814x-Q1EVM shares much of the same design, only the DRV824x-Q1EVM is referenced. The micro-USB connection at the top of the EVM is used for GUI communications, and MCU firmware updates.
