Other Parts Discussed in Thread: BQ24030手册上bq24030 有一个3.3V/20ma 的LDO输出, 但是后面标注着 (Active only if AC or USB is present,) 是不是可以认为这个输出只有在充电时候有效, 电池供电时无效. 但从芯片内部逻辑框图里看, 看不出这里有选择控制. 有没有用过的高手确认一下.

24页有一句话供你参考。
LDO Regulator The bqTINY III-series provides a 3.3-V LDO regulator. This regulator is typically used to power USB transceiver or drivers in portable applications. Note that this LDO is only enabled when either AC or USB inputs are present. If the CE pin is low (chip disabled) and AC or USB is present, the LDO is powered by the battery. This is to ensure low input current when the chip is disabled.
