I am designing a "smart charger" for my personal Android phone. I would like it to be able to adjust the amount of (or turn off) power going to the phone.
The "smart" features would be implemented on the phone, and all communications handled by a device such as the MAX3421E (Ie. Android ADK).
Here's a block diagram:
What is the proper way to communicate with the phone so that the phone's charge circuitry takes as much power as possible (Is this even possible with the Maxim chip)?
