iW629 Product Summary

AC/DC Secondary-Side Controller for Qualcomm^®Quick Charge^TM2.0

USB Interface with Soft-Short Protection

1.0 Features

2.0 Description

● Supports Qualcomm^®Quick Charge^TM2.0 (QC2.0)

technology High Voltage Dedicated Charging Port

(HVDCP)

The iW629 is an AC/DC secondary-side controller compatible

with the Qualcomm Quick Charge 2.0 USB interface and

secondary-to-primary communication protocol, allowing rapid

chargingofQC2.0-enabledmobiledevices.TheiW629resides

on the secondary side of an AC/DC power supply and allows

the adapter to be conﬁgured for multi-level output such as 5V

and 9V, depending on the voltage requested by the mobile

device. It can be used in Dialog’s primary-side controlled AC/

DC systems to achieve fast voltage transition, low no-load

power consumption, and fast dynamic load response.

● Double-layer cable protection:

Secondary side (iW629): Proprietary D+/D- over-

voltage protection (OVP) addresses V_BUSD+/D- soft

shorts

Primary side (iW1780): SmartDefender™ smart

hiccup technology reduces average output power at

fault conditions without latch

The iW629 implements Dialog’s proprietary secondary-to-

primary digital communication technique. When paired with

Dialog’s primary-side iW1780 controller, the iW629 eliminates

the discrete decoders in the primary side, simplifying system

designs. It uses one opto-coupler to transmit all necessary

information for rapid charging, including output voltage

requests, output current limits, output voltage undershoot,

output over-voltage, and fault and reset signals. It also has a

built-in opto-coupler LED driver to minimize the bill of material

cost.

● Proprietary secondary-to-primary digital communication

eliminates discrete decoders in the primary side and

simpliﬁes system designs

● Single opto-coupler transmits all information for rapid

charge: output voltage requests, output current limits,

output voltage undershoot, over-voltage protection,

and fault and reset signals

● Backward compatible with USB Battery Charging

Speciﬁcation Revision 1.2 (USB BC1.2) Dedicated

Charging Port (DCP)

The iW629 and iW1780 provide double-layer cable protection.

On the secondary side, the iW629 incorporates Dialog’s

proprietary D+/D- over-voltage protection to address V_BUSD+/

D- soft shorts. On the primary side, the iW1780 uses Dialog’s

SmartDefender advanced hiccup technology to reduce the

average output power during soft shorts without latch.

● Pin-to-pin compatible with iW626

● Programmable active fast discharge from 9V to 5V at

mobile device (MD) unplug or upon request with built-in

switch or external switch

Dialog’s innovative, proprietary technology ensures that power

supplies designed with the iW629 and iW1780 can provide

multi-level output voltage conﬁguration, with user-selected

various output current limit combinations. Furthermore, the

chipset can achieve <10mW no-load power consumption

at 5V, 2A output setting and fast dynamic load response in

typical AC/DC rapid charge adapter designs.

● Normally OFF state with <120mA cut-off current during

5V steady-state operation to achieve <10mW power

consumption at no load

● Wide operating voltage range from 3V to 25V

● Built-in opto-coupler LED driver with minimum driving

current of 2mA

● 6-lead SOT-23 package

Qualcomm^®Quick Charge^TM2.0 is a product of Qualcomm Technologies, Inc.

3.0 Applications

● Rapid-charging AC/DC adapters for smart phones,

tablets, and other portable devices
