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

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.

Supports Qualcomm^®Quick Charge 2.0

Specification

Secondary-Side Constant Voltage (CV) and

Constant Current (CC) Regulation

Built-in Charge-Pump Circuit for Low Output

Voltage Operation

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.

Internal, Accurate, Adaptive CV/CC Reference

Voltage

Low-Value Current Sensing Resistor for High

Efficiency

The FAN6100Q enables power adaptor’s output

voltage adjustment if it detects a protocol capable

powered 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.

Programmable Cable Voltage Drop

Compensation

Two Operational Transconductance Amplifiers

with Open-Drain Type for Dual-Loop CV/CC

Control

Compatible with Fairchild’s FAN501A

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

supply’s output voltage, V_BUSof 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.

Output Under-Voltage Protection

Low Quiescent Current Consumption in Green

Mode < 850 µA

Wide V_INSupply Voltage Range

Available in 20-Pin 3 x 4 mm MLP Package

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

package.

Applications

Battery Chargers for quick charge application

AC/DC Adapters for Portable Devices that

Require CV/CC Control
