Enter Qualcomm Quick Charge 2.0. Designed to be scalable across different classes of electronics, it is 100% compatible with how charging is done today. Quick Charge 2.0 is connector independent. It requires the D+/D- data lines and can work with USB Type-A, USB micro, USB Type-C and other proprietary connectors. Over 20 OEMs already support this technology and more than 70 accessories are currently available (download PDF list).
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.
This patented technology is designed to use noise-free data lines for effective handshaking and communication, while enabling high-efficiency transfer of electricity. Qualcomm Quick Charge 2.0 is fast, effective and follows a comprehensive certification process. And new, exciting technologies for battery management are still to come as Qualcomm Quick Charge delivers improved charging solutions for smartphone users.
