Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

FAN6100Q Secondary-Side CV/CC Controller Compatible with Qualcomm Quick Charge 2.0 March 2015 FAN6100Q Secondary-Side Constant Voltage and Constant Current Controller Compatible with Qualcomm Quick Charge 2.0 Features Description The FAN6100Q is a integrated secondary side power Supports Qualcomm Quick Charge 2.0 adaptor controller that is compatible with Qualcomm Specification Quick Charge 2.0 Class A technology. It is designed Secondary-Side Constant Voltage (CV) and for use in application that requires Constant Voltage Constant Current (CC) Regulation (CV) and Constant Current (CC) regulation. Built-in Charge-Pump Circuit for Low Output The controller consists of two operational amplifiers Voltage Operation for voltage and current loop regulation with adjustable reference voltage. The CC control loop also Internal, Accurate, Adaptive CV/CC Reference incorporates a current sense amplifier with gain of 10. Voltage Outputs of the CV and CC amplifiers are tied together Low-Value Current Sensing Resistor for High in open drain configuration. Efficiency The FAN6100Q enables power adaptors output Programmable Cable Voltage Drop voltage adjustment if it detects a protocol capable Compensation powered device. It can be capable of outputting 5.0 V at the beginning, and then 9 V or 12 V to meet Two Operational Transconductance Amplifiers requirement of High-Voltage Dedicated Charging Port with Open-Drain Type for Dual-Loop CV/CC (HVDCP) power supply. If a non compliant powered Control device is detected, the controller disables output Compatible with Fairchilds FAN501A voltage adjustment to ensure safe operation with smart phone and tablets that support only 5 V. Adaptive Secondary-Side Output Over-Voltage Protection through Photo-Coupler FAN6100Q also incorporates an internal charge pump circuit to maintain CC regulation down to power Output Under-Voltage Protection supplys output voltage, V of 2 V without an BUS Low Quiescent Current Consumption in Green external voltage supply to the IC. Programmable Mode < 850 A cable voltage drop compensation allows precise CV regulation at the end of a USB cable via adjusting one Wide VIN Supply Voltage Range external resistor.
