RapidCharge™ Dedicated Charging Port Controller for

Qualcomm^®Quick Charge™ 2.0 and Divider Mode

1 Description

The iW632 is a RapidCharge™ Dedicated Charging Port (DCP) controller for Qualcomm^®Quick Charge^TM2.0

(QC2.0) technology, optional Samsung Adaptive Fast Charging (AFC) and divider mode USB interface. It allows

rapid charging of QC2.0 or divider mode enabled mobile devices (MDs), and it automatically identiﬁes QC2.0, AFC

and divider mode protocols. The iW632 resides on the USB port of the power adapter and allows the adapter to be

conﬁgured for multi-level output such as 5V, 9V, or 12V depending on the voltage requested by MD. It can be used

in DC/DC power converter systems to achieve smooth voltage transition and low no-load power consumption. The

iW632 implements three output pins for output feedback ratio change, output over-voltage, and fault and reset signals.

In addition, iW632 also implements proprietary D+/D- over-voltage protection (OVP) and proprietary D- impedance

detection to address soft short issues in the output cables and connectors that can be caused by such things as a

poor or loose connection between the cable connector and the socket, contamination in the USB connector, or a

worn-out cable, and provides protection against the damages.

Dialog’s innovative proprietary technology ensures that power supplies designed with the iW632 can provide multi-

level output voltage conﬁguration, smooth voltage transition and ultra-low no load power consumption.

2 Features

● Proprietary D+/D- OVP and proprietary D-

impedance detection address soft short issues in

the output cables and connectors and provides

protection against damages

● Supports Qualcomm® QC2.0 High Voltage Dedicated

Charging Port (HVDCP) Class A with voltage

conﬁguration of 5V, 9V, and 12V

● Supports divider mode with D+/D- at 2.7V/2.0V for

● Programmable active fast discharge from 9V/12V

to 5V at MD unplug or from a high voltage level to

a lower level upon request with built-in switch or

external switch

2.1A rapid charging

● Optionally supports Samsung Adaptive Fast Charging

(AFC) for output voltage and current negotiation

● Backward compatible with USB Battery Charging

● Normally OFF state with <120µA cut-off current

during 5V steady-state operation to achieve ultra-low

power consumption at no load

Speciﬁcation Revision 1.2 (USB BC1.2) DCP

● Backward compatible with Chinese Telecom Standard

YD/T 1591-2009 Shorted Mode

● Wide operating voltage range from 3V to 25V

● Automatically differentiates MDs and determines rapid

charging protocols

3 Applications

● DC/DC converters/chargers for smart phones, tablets,

and other mobile devices
