CXLB74223 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. CXLB74223 supports the full output voltage range of Quick Charge 3.0, including 200 mV microstepped voltage levels from 3.6 V to 12 V (Class A) . CXLB74223 provides a suite of system level protection features protect- ing the power supply and connected Powered Device (PD) from excessive output voltages, sec- ondary side thermal overload, and faulty power delivery while adapter is unplugged.Additionally it allows the PD to remotely shutdown the power supply through USB data lines. CXLB74223 automatically detects whether a connected PD is Quick Charge 3.0 or Quick Charge 2.0 capable before enabling output voltage adjustment. If a PD that is not compliant to Quick Charge 2.0 or 3.0 is detected, the CXLB74223 disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs.
