The USB to I2C interface is used for communicating between a digital power management device (like the ADP1043A) and the configuration software that runs on a computer. It also supplies 5V and 0.5A to power up the daughter card / evaluation boards.
This same USB to I2C interface connector is used for the ADP1043A, ADP1047, ADP1048, and other digital power management devices.
USB to I2C Interface
The package contains the USB to I2C Interface, and a CD containing the software, application notes and other documents. This is ordered from the ADP1043A page. (This same interface is used on the ADP1047, ADP1048, and other parts.)
