iW636 AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 3.0 USB Interface 1 Description The iW636 is an AC/DC secondary-side controller for USB interface supporting Qualcomm Quick Charge 3.0 (QC3.0) technology and secondary-to-primary communication protocol, to enable rapid charging of QC3.0/QC2.0-enabled mobile devices (MDs). The iW636 resides on the secondary side of an AC/DC power supply and allows the adapter to be configured for multi-level output voltages from 3.6V to 12V in 200mV increments, depending on the voltage requested by the MD. 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. The iW636 implements Dialog’s proprietary secondary-to-primary digital communication technique. When paired with Dialog’s primary-side iW1782 controller, the iW636 eliminates the discrete decoders on the primary side, simplifying system designs. It uses one opto-coupler to transmit all the 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 iW636 and iW1782 provide double-layer cable protection. On the secondary side, the iW636 incorporates Dialog’s proprietary D+/D- over-voltage protection to address VBUS D+/D- soft shorts. On the primary side, the iW1782 uses Dialog’s SmartDefenderTM advanced hiccup technology to reduce the average output power during soft shorts without latch. Dialog’s innovative, proprietary technology ensures that power supplies designed with the iW636 and iW1782 can provide multi-level output voltage configuration, with user-selected various output current limit combinations. Additionally, 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. 2 Features ●● Supports Qualcomm® Quick ChargeTM 3.0 technology High Voltage Dedicated Charging Port (HVDCP) to provide VBUS from 3.6V to 12V in 200mV increments ●● Adaptive OVP/UV detection for most VBUS levels ●● Double-layer cable protection: ●● Pin-to-pin compatible with iW626 xx Secondary side (iW636): Proprietary D+/D- overvoltage protection (OVP) addresses VBUS D+/Dsoft shorts xx Primary side (iW1782): 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 ●● Backward compatible with QC2.0 and USB Battery Charging Specification Revision 1.2 (USB BC1.2) ●● Programmable active fast discharge from a high voltage VBUS level to 5V at MD unplug or upon request with built-in switch or external switch ●● Normally OFF state with <150µA cut-off current during 5V steady-state operation to achieve <10mW overall system no-load power consumption ●● Wide operating voltage range from 3V to 16V ●● Single opto-coupler transmits all information for rapid charge: output voltage requests, output current limits, output voltage undershoot (UV), over-voltage protection (OVP), and fault and reset signals ●● Built-in opto-coupler LED driver with minimum driving current of 2mA ●● 6-lead SOT-23 package 3 Applications ●● Rapid-charging AC/DC adapters for smart phones, tablets, and other portable devices Qualcomm® Quick ChargeTM 3.0 is a product of Qualcomm Technologies, Inc.
