The BQ25970YFFT is a battery management I2C 1 cell 8A switched capacitor (SCC) battery charger for parallel charging applications with external over voltage protection (OVP) support. It is manufactured by Texas Instruments and comes in a 56-DSBGA package. It operates in a temperature range of -40C to 85C. This device allows for simultaneous charging of two batteries in parallel, enabling a boosting effect in which both batteries are charged faster than if only a single battery were charged in series. It supports various battery types including Li-Ion, Li-Polymer, Lead Acid, and NiMH. It features a Constant Voltage/Constant Current Control Loop, programmable recharge threshold, programmable overvoltage protection, and thermal overload protection. The BQ25970YFFT includes robust diagnostic features such as Charge Safety Timer, Overvoltage Protection, Undervoltage Protection, Short-Circuit Protection, and Temperature Protection.
