PCA9306: PCA9306 as a switch to control the resolution of the I2C interface

Part Number: PCA9306

Hello.

Is this correct if in DS for PCA9306 on figure 8 VDPU will be 1.8V?

I need to use PCA9306 as a switch to control the resolution of the I2C interface with a supply voltage of 1.8V.

I needed the resolution of the I2C interface to solve the problem of an incorrect initial state of I2C Bus Master.

I'll provide the 3.3V enable signal.

I do not need to separate the line capacity.

 

Or so it is more correct?

  • Hey Alexander,

    In both your figures the issue you have is the enable signal is 3.3V. If you change the enable signal to be 1.8V then this will work.


    Thanks,
    -Bobby
