The BQ27441EVM-G1B evaluation module is a complete evaluation system for the bq27441-G1B. The EVM includes one bq27441-G1B circuit module with an external current-sense resistor. The bq27441-G1B should be used with batteries that have a 4.3 or 4.35 V charge voltage. A separate 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 includes one bq27441-G1B 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 EV2400 interface board and software, the user can: (1)Read the bq27441-G1B data registers. (2)Program the chipset for different configurations. (3)Log cycling data for further evaluation. (4)Evaluate the overall functionality of the bq27441-G1B 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.

  • Populated circuit module for quick setup and evaluation.
  • Downloadable software that can be used for data logging and analysis.
