bq34110EVM-796 Evaluation Module
This evaluation module (EVM) is a complete evaluation system for the bq34110. This EVM includes one
bq34110 circuit module, an external current sense resistor. A separate orderable EV2400 PC interface
board for gas gauge along with a PC USB cable, and Microsoft
®
Windows
®
based PC software is needed
when using this EVM. The circuit module includes one bq34110 integrated circuit and all other onboard
components necessary to monitor and predict capacity for a system-side or removable battery pack fuel
gauge solution. With the EV2400 users can:
• Read the bq34110 data registers
• Program the chipset for different configurations
• Log cycling data for further evaluation
• Evaluate the overall functionality under different charge and discharge conditions
