Hi team,

Is there only one I2C address for the TUSB216-Q?

If two TUSB216 devices need to be controlled by the same I2C bus, is there a way to achieve this?

Thanks

Hi Xiaoxiang,

Yes, there is only one I2C address from the TUSB216-Q1. You can get a mux to help with the pathing of these I2C lines so that you can program both even though they have the same I2C address. I would recommend looking at the TMUX121: https://www.ti.com/product/TMUX121.

Thanks,

Ryan
