ChiPhy™ family is a USB mobile device charger interface IC which implements the Qualcomm’s Quick Charge 3.0 specification for adaptive voltage battery charging. It incorporates all necessary functions to add Quick Charge 3.0 capability to circuits incorporating Power Integrations’ switcher ICs such as InnoSwitch, TinySwitch, TOPSwitch and other charger solutions employing traditional secondary-side feedback schemes. CHY103 supports the full output voltage range of Quick Charge 3.0, including 200mV micro-stepped voltage levels from 3.6V to 12V (Class A) and up to 20V (Class B). CHY103 provides a suite of system level protection features protecting the power supply and connected Powered Device (PD) from excessive output voltages, secondary-side thermal overload, and faulty power delivery while adapter is unplugged. Used in battery chargers for smart phones, tablets, netbooks, digital cameras, Bluetooth accessories and USB power output ports such as battery banks or car chargers.
