Hello,
I am using the TCA9458A with the Coloumb Counter on the I2C Mux interfaces. The coulomb counter is powered off of it's sense+ and sense- pins. The sense lines are active enabling an internal pull-up on the data lines to 2V while the Vin and data pull-up rail is inactive. I have reason to believe this is causing backpowering from SCX and SDX to Vin on the TCA9458A. Is backpowering from the muxxed data lines to Vin a known issue on the TCA9548A?
Thanks
