iW629 Product Summary AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 2.0 USB Interface with Soft-Short Protection 1.0 Features 2.0 Description ●● Supports Qualcomm® Quick ChargeTM 2.0 (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 charging of QC2.0-enabled mobile devices. The iW629 resides 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: xx Secondary side (iW629): Proprietary D+/D- overvoltage protection (OVP) addresses VBUS D+/D- soft shorts xx Primary side (iW1780): SmartDefender™ smart hiccup technology reduces average output power at fault conditions without latch ●● 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) ●● 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 The iW629 implements Dialog’s proprietary secondary-toprimary 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. 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 VBUS D+/ 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. ●● Built-in opto-coupler LED driver with minimum driving current of 2mA 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. ●● 6-lead SOT-23 package Qualcomm® Quick ChargeTM 2.0 is a product of Qualcomm Technologies, Inc. ●● 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 3.0 Applications ●● Rapid-charging AC/DC adapters for smart phones, tablets, and other portable devices iW629 Product Summary Rev. 0.5 Preliminary 1 of 6 © 2015 Dialog Semiconductor (UK) Ltd. iW629 Product Summary AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 2.0 USB Interface with Soft-Short Protection L VOUT + + N RTN U1 iW1780 NTC 2 1 VCC 3 DRV DIS GND 7 D- GND D+ 4 5 6 1 VSENSE 2 SD 3 DLNK OUTPUT 6 4 ASU CS/CDC 5 VCC 8 + U2 iW629 RCDC D+ D- Figure 3.1: iW629 Typical Application Circuit for Multi-Level Output Voltage and Current (Using iW1780 as Primary-Side Controller.
