2 bq27220EVM Quick Start Guide
This section provides the step-by-step procedures required to take a new EVM and configure it for
operation in a laboratory environment.
2.1 Items Needed for EVM Setup and Evaluation
The following items are required for setup and evaluation of the EVM:
• bq27220 circuit module
• EV2300 or EV2400 communications interface adapter
• USB cable to the communications interface adapter to the computer
• Computer setup with Windows XP or higher operating system
• Access to the internet to download bqStudio software setup program
• DC power supply capable of supplying 4.5 V and 2 A. (Constant current and constant voltage
capability is desirable.)
2.2 System Requirements
The bqStudio software requires Windows XP or later. Using later versions of the Windows operating
system can cause issues with the USB driver support. The EV2300 USB drivers have been tested for
Windows 98SE, but no assurance is made for problem-free operation with specific system configurations.
2.3 Software Installation
Find the latest software version of bqStudio on http://www.ti.com/tool/bqstudio. Search by part number for
bq27220 to access the tool folder for the device. Use the following steps to install the bq27220 bqStudio
software:
1. Ensure that the EV2300 or EV2400 is not connected to the personal computer (PC) through the USB
cable before starting this procedure.
2. Open the archive containing the installation package, and copy its contents into a temporary directory.
3. Open the bqStudio installer file that was downloaded from the TI Web site.
4. Follow the on-screen instructions until completing the software installation.
5. Before starting the evaluation software, connect the EV2300 or EV2400 to the computer using the USB
cable.
6. If EV2300 is connected, wait until the system prompt New Hardware Found appears. Choose Select
Location Manually, and use the Browse button to point to the TIUSBWin2K-XP-1 subdirectory.
7. Answer Continue to the warning that drivers are not certified with Microsoft.
8. If the EV2300 is connected, after the previous installation finishes, another system prompt New
Hardware Found appears. Repeat steps 1 through 5, but specify the directory as TIUSBWin2K-XP-2.
9. Answer Continue to the warning that drivers are not certified with Microsoft. Driver installation is now
finished.
10. For the EV2400, the driver should be installed along with software installation.
2.4 Troubleshooting Unexpected Dialog Boxes
Log in as administrator before downloading the files. The driver is not signed, so the administrator must
allow installation of unsigned drivers in the operating system. If using Windows 7, install the software with
administrator privileges.
2.5 EVM Connections
The bq27220 evaluation system comprises three hardware components: the bq27220 circuit module, the
EV2300 or EV2400 PC interface board, and the PC.
