bq4050EVM-561 Evaluation Module
This evaluation module (EVM) is a complete evaluation system for the bq4050. This EVM includes one
bq4050 circuit module and an external current-sense resistor. A separate orderable EV2300 or 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 bq4050 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 EV2300 or EV2400 users can:
• Read the bq4050 data registers
• Program the chipset for different configurations
• Log cycling data for further evaluation
• Evaluate the overall functionality under different charge and discharge conditions
