I've designed a board, that includes a charging part :
here I can measure 5V on Pin1, but nothing on pin2, I was expecting 3.3V : I've check the board and no I don't have any bypass, to test the board, I've put a 3.3V voltage at "target voltage pin" and the board works fine! So my question is how may solve this and what am I missing! This the layout part!
and here a link to the datasheet
