您好，请教一下，TPS4811x的自举电容C(BST)充电路径是什么？
根据规格书的框图，Charge pump流经BST给自举电容充电，但我不太清楚自举电容流回电池GND的路径是什么呢？特别是当输出端口没有阻性负载（比如悬空）的时候，此时我们板子上的NMOS也可以打开，说明自举电容充了电，那么充电路径是什么呢？
谢谢！

您好！
电流路径与您为自举电容器消耗的路径相同。 当 FET 关断时、PD 会短接至 SRC、因此栅极电压等于 SRC。 电荷泵电流从内部流经 SRC 引脚流回电荷泵。 这被视为一个悬空节点、其中电荷泵位于 VS 和 SRC 引脚之间。 电流将永远不会返回到电池 GND。
谢谢！
