bq27411 EVM: System-Side Impedance Track™
Technology
This evaluation module (EVM) is a complete evaluation system for the bq27411 fuel gauge. The EVM
includes one bq27411 circuit module with a current-sense resistor. A separate orderable EV2300 or
EV2400 PC interface board for fuel gauge interface along with a PC USB cable, and Microsoft
®
Windows
®
based PC software is needed when using this EVM. The circuit module includes one bq27411 integrated
circuit and all other onboard components necessary to monitor and predict capacity for a pack-side fuel
gauge solution. The circuit module connects directly across the battery cell. With the EV2300 or EV2400
interface board and software, the user can:
•
Read the bq27411 data registers
•
Update the RAM for different configurations
•
Log cycling data for further evaluation
•
Evaluate the overall functionality of the bq27411 solution under different charge and discharge
conditions
The latest Windows-based PC software can be downloaded from the product folder on the Texas
Instruments Web site.
