bq24170充电一段时间后，就不充电了，指示灯闪烁，必须把适配器重新插拔，然后就有正常了，过段时间又出现了。看手册应该是短路保护了 ，
The IC has a short circuit protection feature. Its cycle-by-cycle current monitoring feature is achieved through
monitoring the voltage drop across Rdson of the MOSFETs. The charger will be latched off, but the ACFET keep
on to power the system. The only way to reset the charger from latch-off status is remove adapter then plug
adapter in again. Meanwhile, STAT is blinking to report the fault condition
手册上有这样的话 ，可是 Rdson of the MOSFETs.是哪个地方的电压啊 ，知道这是什么原因导致的吗
