TCA9548A: Multiple Levels of I2C Switch

Tool/software:

Hello, I want to ask the forum members if this will work. I am using a Eval kit that is using one TCA9548A. From that device I connect one of the channels to another TCA9548A. Will that be a problem?

I am using several INA233 power monitors that have the same I2C addresses so I plan to only enable one channel at a time to read those monitors so there will be no I2C address conflicks.

Does this sound like it will work?

Thank you very much,

Joe

Hi joe,

This application should be fine and is something that is commonly done to avoid address conflict in i2c applications

Here is a appnote and e2e post that talks about this in more detail and there shouldn't be any issues with this application

Please let me know if you have any additional questions and I can help more if needed.

Regards,

Kameron
