在datasheet中有这样一段描述"When the adapter is removed, the IC turns off ACFET and enters SLEEP mode.
BATFET keeps off until the system drops close to SRN. The BATDRV pin is driven to ACN - 6V by an internal
regulator to turn on P-channel BATFET , connecting the battery to the system."
就是说我拔下适配器后，电池需要一定时间才会接入系统，系统有一段时间是没电的吗，怎么才能做到系统一直不断电呢？
