[GD] FAN6100Q Qualcomm® Quick Charge 2.0

요즘 나오는 Qualcomm 고속 충전기를 어떻게 잘 사용해볼 방법이 없을까 싶어서 조사중입니다..

충전기측 IC Datasheet

단순히 DP,DN 단을 아래와 같이 충전기측에 설정 해주면 충전 전원이 저렇게 나오지 않을까 싶은데....

나중에 고속 충전기 구해서 테스트가 필요 할듯...

Secondary-Side Constant Voltage and Constant Current Controller Compatible with Qualcomm® Quick Charge 2.0

The FAN6100Q is a integrated secondary side power adaptor controller that is compatible with Qualcomm® Quick Charge™ 2.0 Class A technology. It is designed for use in application that requires Constant Voltage (CV) and Constant Current (CC) regulation.

The controller consists of two operational amplifiers for voltage and current loop regulation with adjustable reference voltage. The CC control loop also incorporates a current sense amplifier with gain of 10. Outputs of the CV and CC amplifiers are tied together in open drain configuration.

The FAN6100Q enables power adaptor’s output voltage adjustment if it detects a protocol capable powerd device. It can be capable of outputting 5.0 V at the beginning, and then 9 V or 12 V to meet requirement of High-Voltage Dedicated Charging Port (HVDCP) power supply. If a non compliant powered device is detected, the controller disables output voltage adjustment to ensure safe operation with smart phone and tablets that support only 5 V.

FAN6100Q also incorporates an internal charge pump circuit to maintain CC regulation down to power supply’s output voltage, VBUS of 2 V without an external voltage supply to the IC. Programmable cable voltage drop compensation allows precise CV regulation at the end of a USB cable via adjusting one external resistor.

The device is available in the 20-pin MLP 3 x 4 package.
