Evaluation Kits

EVAL-ADP-I2C-USB

USB to I2C Interface Connector

Product Details

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.
