In LiPo_Charger_LS_TP4056_schematic.pdf we can see the power path doesn't have USB charger 5v as input. Maybe I'm wrong but shouldn't be the load supplied by the charger will the USB cable is connected?

Hi, the charging input (+5V) is passed to the output (VOUT) via the diode (D1). At the same time, the charging input is connected to the gate of the MOSFET (Q2), thus switching off the connection to the battery (B+).

Ohh thank you, I've missed that! great! is it possible to use your design and order it from JLC-PCB or PCB way? Is it an open design?

As a comment it would be nice to have a lipo charger with load sharing, battery protection and output either on 5v or 3v3 if some day you look for something to do :)

Thanks in any case!

Yes, of course, it's all open source.
I'll put it on my to-do list, which is pretty long now ;-)
