Title: Qualcomm QuickCharge 3/4/5 Interface Specification
Post by: horvat.kamca on April 28, 2021, 08:50:38 am

I'm a bit curious about how QuickCharge 4 and 5 works. Unfortunately, I was not able to find quickcharge specification. The only thing I found is reference to these documents in TEA19051BTK datasheet.

[6] Qualcomm® QuickCharge™ 3.0 Interface Specification — 80-NH008-2, revision K; Qualcomm®, August 1, 2017
[7] Qualcomm® QuickCharge™ 4 Interface Specification — 80-NH008-3, revision D; Qualcomm®, August 1, 2017

Can you point me to where these documents can be obtained?

Pretty sure these are closed source, need to sign NDAs etc. On the contrary, USB PD is all out in the open.
