Aseem,
TI also has a few I2C multiplexers that can be useful for situations like this. Using a device like the PCA9548A (1 to 8 I2C mux) will allow you to get 8 x the number of devices you would ordinarily get on one I2C bus. Up to 8 PCA9548A devices…
Other Parts Discussed in Thread: PCA9543A , PCA9544A , PCA9545A , PCA9546A , PCA9548A No, this will cause problems with the ACKs from the devices.
If the device in question only has one I2C address available, then you will need to use an I2C address…
I wanted to mention that this applies to all the series of switches PCA9543A, PCA9544A, PCA9545A, and PCA9548A series of I2C switches. I wanted to get these part numbers in this thread in case somebody searches for it.

Hi,
I have connected 2 sensors# HDC2022 (ADDR = 0x40 and 0x41) to each output of 1 X 8 I2C multiplexer (PCA9548 through Arduino - total = 16 sensors) , and trying to read the data from…
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…
vc707_Schematic_xtp135_rev1_0.pdf Thank you for your reply.But I do not know the specific function of SEQ.For example,there are three ucd9248 in schematic of vc707 evaluation kit.I found that the SEQ-1 and SEQ-2 of all chips are connected together while…
