Other Parts Discussed in Thread: BQ2060A, PCA9548A

Hello,

is it possible to change the SMBus ID adress ?

I need to use up to 5 batteriepacks, each equipped with the bq2060A, in parallel circuit and want to transfer the battery data of each battery via one SMBus to the PC.

Thanks for helping!

Stefan

    Hello Stefan,

    No, the device address for the bq2060A cannot be changed.  I suggest you use an I2C multiplexer IC that will allow you to change the port connected to the SMBus by a command to the multiplexer IC.  TI makes a part like this.  Try using the 8-channel PCA9548A.
