This evaluation module (EVM) is a complete evaluation system for the bq27220. This EVM includes one
bq27220 circuit module, 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
needed when using this EVM. The circuit module includes one bq27220 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 bq27220 data registers
•
Program the chipset for different configurations
•
Log cycling data for further evaluation
•
Evaluate the overall functionality under different charge and discharge conditions
