Part Number:TPS2120Other Parts Discussed in Thread:TPS2044B, TPS2561, LM3544
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。
