Texas Instruments  BQ27426EVM-738

The BQ27426EVM-738 evaluation module is a complete evaluation system for the bq27426. The EVM includes one bq27426 circuit module with an external sense resistor. A separated orderable 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 connects directly across the battery pack. With the EV2400 interface board and software, the user can: (1)Read the bq27426 data registers. (2)Program the chipset for different configurations. (3)Log cycling data for further evaluation. (4)Evaluate the overall functionality of the bq27426 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.
