Texas Instruments bq2577xGEVM Controller Evaluation Module (EVM)

Texas Instruments bq2577xGEVM Controller Evaluation Module (EVM) is designed to evaluate the bq2577xG. The bq2577xG is a high-power, high-efficiency battery charge controller. The evaluation module drives GAN FETs for high efficiency. The input voltage range is from 3.5V to 40V, with a programmable output of 2 to 5 cells and a charge current range of 0A to 16.3A. This bq2577xGEVM allows the user to evaluate the function and performance of the bq2577xG with step-by-step instructions. The Texas Instruments bq2577xGEVM also serves as a reference design with a complete schematic, layout, and Bill of Materials (BOM).
