Texas Instruments BQ27421EVM-G1A

System-Side Battery Fuel (Gas) Gauge Solution Evaluation Module

The BQ27421EVM-G1A evaluation module is a complete evaluation system for the bq27421. The EVM includes one bq27421 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 bq27421 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: (1)Read the bq27421 data registers. (2)Program the chipset for different configurations. (3)Log cycling data for further evaluation. (4)Evaluate the overall functionality of the bq27421 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.
