Wall charger interface ic cuts smartphone charge time by 75%
The CHY100 from Power Integrations is an ac/dc wall charger interface ic that enables designers of mobile devices to implement the Quick Charge 2.0 protocol from Qualcomm.

The company claims the device enables users to charge mobile devices up to 75% faster than when using conventional technology.
It works by detecting commands from a Quick Charge 2.0 enabled device, such as a mobile phone handset, and adjusting the output of the ac/dc wall charger to enable increased power delivery to the device's battery.
When plugged into a powered device without Quick Charge 2.0 capability, the CHY100 automatically disables the higher voltage/higher power capability to ensure safe operation.
Available in an SOIC-8 package, the module is suitable for battery chargers for smartphones, tablets, netbooks, digital cameras and Bluetooth accessories, as well as usb power output ports.
