Qualcomm Technologies, Inc. has claimed the fastest commercial charging technology for Android phones. The Quick Charge 5 charger enables users to charge devices from 0 to 50 percent battery power in just five minutes. This makes the charger up to 70 percent more efficient than its predecessor, the Quick Charge 4, and up to four times faster than the previous generation.
The new platform supports 2S batteries and 20 volts (V) of power delivery. It also enables new battery technology, accessories, and safety features. These include 12 separate voltage, current and temperature protections, including USB-input overvoltage protection at 25 V and external power controls beyond 30 V. It also runs 10°C cooler than the Quick Charge 4.
Quick Charge 5 incorporates Dual/Triple Charge technology, adaptive input voltage, INOV4, Qualcomm Battery Saver, and the new Qualcomm Smart Identification of Adapter Capabilities. These technologies work together to maximize power transfer efficiency, increase safety, and help extend the battery life cycle, said Qualcomm.
Qualcomm also introduced its next-generation premium power management ICs (PMICs), the Qualcomm SMB1396 and Qualcomm SMB1398. These devices provide maximum efficiency above 98 percent. They support 1SnP and 2SnP batteries, wired and wireless input paths, adaptive operation based on the power source (3 level buck and DIV/2), and scalability (primary and secondary to provide higher power). They also offer higher than 20-V input voltage operation for both wireless and wired power sources.
Quick Charge 5 is backwards compatible with Quick Charge 2.0, 3.0, 4, 4+ and existing handsets powered by the Qualcomm Snapdragon mobile platform. It is supported on Snapdragon 865, 865 Plus, and future premium- and high-tier Snapdragon mobile platforms. The solution is currently sampling with customers and will be available in commercial devices in Q3 2020.
