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
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
