What are the differences between the Pump Express fast filling technology and high pass QC2.0?


Qualcomm QC2.0 uses USB port D+ and D- to realize a voltage regulation, while the Pump Express fast charging technology of MediaTek is communicating with the charger through USB port VBUS, and applies the corresponding output voltage.


 QC2.0 communicates by configuring D+ and D- voltage. Pump Express communicates with current pulses on VBUS, but the ultimate goal is to increase the charger's voltage to 5V, 7V and 9V.
