Is there a host processor available to perform I2C communication?

Thank you for a promt reply
We would be needing a Resistor to set the current , no micro controller to perform I2C

Also i received a new update from the customer , as they want to make it compatible with any battery , they are using a buck converter before the charger
This buck converter will step down the high voltage battery (12,24,48) down to 5V .
The input of this charger ic shall be connected to this 5V
Thank you
