Qualcomm Quick Charge 2.0

In the Quick Charge spirit of saving you time, Qualcomm Quick Charge 2.0, a super-fast battery charging technology, can charge devices up to 75% faster than a conventional charger. Traditional USB charging is limited to 5 volts and less than 2 amps. In addition, the actual power available for battery charging will be less than 7.5 watts, taking into account losses in the system as well as cables and connector.

Unlike conventional USB charging methods, a Quick Charge 2.0 end-to-end solution takes advantage of higher power levels to quickly and effectively charge devices. Quick Charge 2.0 Class A can provide up to 24 watts over a micro USB connector, 36 watts with a Type-C connector, and Class B can reach 60 watts or more. Future charging advancements are expected to show even further improvement.

With multiple levels of voltage limiting, current limiting and temperature protection, Qualcomm Quick Charge 2.0 is uniquely designed to ensure healthy battery life cycles regardless of connector. All of this is integrated in Quick Charge 2.0 components – no need for external ones.

Implementing Quick Charge 2.0 is often a simple, low-cost charging solution. It’s already implemented into many Qualcomm Technologies PMICs (power management integrated circuits), where it is verified and tested for a mobile device, whereas other solutions require more space on the PCB for extra circuitry.
