The BQ27425EVM-G2A evaluation module is a complete evaluation system for the bq27425-G2A. The EVM includes one bq27425-G2A circuit module with an integrated current-sense resistor. A separated orderable EV2300 or EV2400 PC interface board for gas gauge interface along with a PC USB cable, and Windows™-based PC software is needed when using this EVM. The circuit module includes one bq27425-G2A integrated circuit and all other onboard components necessary to monitor and predict capacity for a system-side fuel gauge solution. The circuit module connects directly across the battery pack. With the EV2300 or EV2400 interface board and software, the user can:
- Read the bq27425 data registers.
- Program the chipset for different configurations.
- Log cycling data for further evaluation.
- Evaluate the overall functionality of the bq27425 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.
