数据： 具有电源路径管理功能和 I2C 接口的 bq2416xx 2.5A、双输入、单节电池开关模式锂离子电池充电器 数据表 (Rev. G)
bq24160，bq24160A，bq24161，bq24161B，bq24163和bq24168是高度集成的单节锂离子电池充电器和系统电源路径管理器件，适用于采用高容量电池的空间受限型便携式应用。此单节电池充电器具有双输入，可由USB端口或更高功率的输入电源（即交流适配器或无线充电输入）供电，适用于多用途解决方案。两个输入彼此完全隔离，并可以使用I 2 C接口方便地进行选择。
电源路径管理功能使得bq2416xx能够对对电池进行独立充电的同时通过一个高效的直流/直流转换器为系统供电。电源路径管理架构使系统能够采用有缺陷的电池组或在电池组缺失的情况下运行，并且即使在电池完全放电或者无电池的情况下也可实现即时系统启动。
