Hey all,
I want to build a 18W QC3.0 compatible powerbank, while there are already many options available in the market I want to take up this project as it will help learn something new...
There aren't many reference designs online(available for QC3.0 for wall chargers but not for powerbanks).
What would be the major components required?
1)Battery Gauges(bms)
2)Battery Charge Controller
3)QC3.0 compatible USB Type A controllers
4) A 8-bit MCU to read the SOC information from gauge and display it to a numerical lcd
5) Numerical LCD
I am looking at Ti product offerings for the charge controllers and battery gauges. I am not able to find any QC3.0 compatible controllers. Would be great if I can get some recommendations.
Since the Battery Gauges will be providing OC,OV,UVLO,OT protections, can I pick a usb controller without the protection features?
What else should consider?
Thanks
