BQ40Z80能够实现在休眠状态下，当充电器插入或者负载接入时，唤醒休眠状态下的BQ40Z80吗？
再就是BQ40Z80芯片的BATTERY PACK REMOVED Mode/System Present Detection 功能怎样理解，能帮忙解析一下吗？谢谢
您好，从sleep mode下唤醒的方法请参考TRM 6.3SLEEPMode

BATTERY PACK REMOVED Mode 当[NR]=0, PRES 输出是高的状态相当于电池没有接入。
System Presen主要是PRES正常情况下是接到系统，但是在没有系统的情况下做充放电测试PRES需要接到地。
PRES: Connect to host to detect system present input for a removable battery pack. Do not pull up this pin
