PiSupply/PiJuice

is USB power input limited to 1.75A (and J4 to 2.75A) ?

Opened this issue · 1 comments

Reading the IC's documentation (page 6 on https://github.com/PiSupply/PiJuice/blob/master/Hardware/Datasheets/BQ24160RGET.pdf ), I read that USB power input was limited to 1.75A, and J4 power input to 2.75A.

Yes, on Pijuice schematic ( https://github.com/PiSupply/PiJuice/blob/master/Documentation/PiJuice_Schematic.PDF ), it seems that power lines of both entries are connected and so should share the same maximum.

Am I missing something? What is the max power input via micro-USB ?
Thanks for your help!

@shawaj : I would appreciate support on this, please.
