Original question:
HD3SS6126两级级联问题
I only find Dual-Input, Single-Output (DISO) Power Multiplexer, such as TPS212x devices.
Is there a Single-Input, Multi-Output(1:2 or 1:4) Power Multiplexer?
I used to design a USB demultiplexer
Hi 用USB电源开关就可以：

按照你的需求选择开关数目既可以找到合适芯片。
谢谢，筛选了下，感觉LM3544、TPS2561、TPS2044B，都符合我要求，请问下这几款有啥区别呢？
HI 主要就是通道数， 电流限制等等不同，具体直接比较datasheet就一目了然了。
