The BQ2569X/9X-Q1 evaluation module (EVM) is used to evaluate the BQ2569X/9X-Q1 integrated circuit. The BQ2569X/9X-Q1 is an integrated switched-mode buck-boost battery charge management device in HOTROD (QFN) package, intended for charging 1-series to 7-series cell Li chemistry batteries with up to 3.3A charge current. In forward/charge/sink mode, the IC operates from 2.5V to 36V input voltage and withstands up to 45V. The default charge voltage and current are set using resistors. The device defaults to forward/charge/sink mode but can be changed using I2C to reverse/OTG/source mode. In addition, the I2C registers can change the switching frequency as well as the voltage and current regulation settings.
