bq25798 I2C Buck-Boost Solar Battery Charger

Texas Instruments bq25798 I2C Buck-Boost Solar Battery Charger is a fully integrated switch-mode buck-boost charger for 1-4 cell Li-ion batteries and Li-polymer batteries. The integration includes four switching MOSFETs, input and charging current sensing circuits, the battery FET, and all the loop compensation of the buck-boost converter. It uses NVDC power path management, regulating the system not dropping below a configurable minimum system voltage. When system power exceeds the input source rating, battery supplement mode supports the system without overloading the input source. bq25798 also maximizes the power from photovoltaic panels using its built-in VOC scaling MPPT algorithm. bq25798 supports ultra-fast switchover from the adapter to a converted battery voltage in Backup Mode.
