Hi NXP expert,

I would like to know whether CBTU02044 support hot plug, could you please help to confirm ?  I found the following description in the datasheet.

 

"Back current protection on all I/O pins of these switches"

Hi

A host system which supports hot plug can/should detect an endpoint/device plugging/adding to it, and support the device (with power, status update, etc.), without having to turn off /reset system power.

   Hot-plug is a system function, I don’t think it is relevant to the MUX, because CBTU02044 doesn’t do detection, no register, no interrupt pinout……

 The system can switch the MUX channel to connect to new endpoint/device without reset the power.
