TCA9548A: Hot swap function

Qiang Ren

Part Number: TCA9548A
Other Parts Discussed in Thread: TCA4307

Team,

i want to check about the tca8548 function, can you share with me the device internal function diagram, which is used to support hot swap function? And is there any particular external circuit needed to support the hot swap?

Thanks,

Qiang

This device does not have a hot-swap function. The controller must disable any channels where you want to do hot (un)plugging.

Hi Qiang,

The device functional diagram is located on page 13 of the datasheet. That being said, this device does not support hot-swap. You can look into devices such as the TCA9511 and TCA4307 which do implement hot-swap.

Regards,

Alex
