I am trying to build a circuit that I can communicate and charge a LiPoly battery over USB. I want to use the FT232RL chip because of its driver support and its FTDIChip-ID feature. I can use either 3.3v or 5v (my sensors come in both varieties). The LiPoly is a single cell battery.
I have looked for diagrams that show this circuit but have had no luck. I find ones that charge over USB and ones that power/communicate over USB. I know this is possible because my phone and mp3 player both do it.
I tried to take a stab at building the circuit myself. Ignore the labeling on the battery and the ferrite bead (I am new to eagle cad and picked the first available symbol)
