數據: 具有電源路徑管理功能和 I2C 接口的 bq2416xx 2.5A、雙輸入、單節電池開關模式鋰離子電池充電器 數據表 (Rev. G)
bq24160,bq24160A,bq24161,bq24161B,bq24163和bq24168是高度集成的單節鋰離子電池充電器和系統電源路徑管理器件,適用于采用高容量電池的空間受限型便攜式應用。此單節電池充電器具有雙輸入,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。兩個輸入彼此完全隔離,并可以使用I 2 C接口方便地進行選擇。
電源路徑管理功能使得bq2416xx能夠對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系統能夠采用有缺陷的電池組或在電池組缺失的情況下運行,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。
