BQ24160、BQ24160A、BQ24161、BQ24161B、BQ24163 和 BQ24168 是高度集成的單芯鋰離子電池充電器和系統電源路徑管理器件，旨在用于空間有限且具有高容量電池的便攜式應用。此單芯充電器具有雙輸入，可由 USB 端口或更高功率的輸入電源（即交流適配器或無線充電輸入）供電，適用于多用途解決方案。這兩個輸入彼此完全隔離，并可以使用 I2C 接口方便地進行選擇。
憑借電源路徑管理功能，BQ2416xx 能夠在對電池進行獨立充電的同時通過一個高效的直流/直流轉換器為系統供電。電源路徑管理架構使該系統能夠在電池包有缺陷或缺失的情況下運行，并且即使在電池完全放電或者無電池的情況下也可實現即時系統啟動。
