4.2 Software System Requirements

The bq27531EVSW software requires 32-bit versions of Windows 2000 or Windows XP. Drivers for

Windows 98SE are provided, but Microsoft™ no longer supports Windows 98; therefore, Windows 98 can

have issues with 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.

4.3 Software Installation

Find the latest software version in the bq27531 tool folder on power.ti.com. Make a search by part number

for bq27531 to access the tool folder.

use the “browse” button to point to subdirectory TIUSBWin2K-XP-1.

8. After installation finishes, another system prompt "new hardware found" appears. Repeat steps 6 and

finished.
