bq25302 Single-Cell Buck Battery Charger

Texas Instruments bq25302 Single-Cell Buck Battery Charger is a highly integrated standalone switch-mode battery charger for single-cell Li-Ion and Li-polymer batteries. The bq25302 supports 4.1V to 6.2V input voltage and 2A fast charge. The integrated current sensing topology of the device enables high charge efficiency and low BOM cost. The best-in-class 200nA low quiescent current of the device conserves battery energy and maximizes the shelf time for portable devices. Its input voltage regulation delivers maximum charging power to the battery from the input source. The solution is highly integrated with an input reverse-blocking FET (RBFET, Q1), high-side switching FET (HSFET, Q2), and low-side switching FET (LSFET, Q3). The Texas Instruments bq25302 is available in a 3mm x 3mm WQFN package for an easy 2-layer layout and space-limited applications.
