1 of 7 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 confgured 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 dialogs primary-side controlled ac/ dc systems to achieve fast voltage transition, low no-load power consumption, and fast dynamic load response. the IW636 implements dialogs proprietary secondary-to-primary digital communication technique. when paired with dialogs 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 dialogs proprietary d+/d- over-voltage protection to address v bus d+/d- soft shorts. on the primary side, the iw1782 uses dialogs smartdefender tm advanced hiccup technology to reduce the average output power during soft shorts without latch. dialogs innovative, proprietary technology ensures that power supplies designed with the IW636 and iw1782 can provide multi-level output voltage confguration, 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 charge tm 3.0 technology high voltage dedicated charging port (hvdcp) to provide v bus from 3.6v to 12v in 200mv increments double-layer cable protection: x secondary side (IW636): proprietary d+/d- over- voltage protection (ovp) addresses v bus d+/d- soft shorts x 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 simplifes system designs 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 3 applications rapid-charging ac/dc adapters for smart phones, tablets, and other portable devices adaptive ovp/uv detection for most v bus levels backward compatible with qc2.0 and usb battery charging specifcation revision 1.2 (usb bc1.2) pin-to-pin compatible with iw626 programmable active fast discharge from a high voltage v bus level to 5v at md unplug or upon request with built-in switch or external switch normally off state with <150a 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 built-in opto-coupler led driver with minimum driving current of 2ma 6-lead sot-23 package qualcomm ? quick charge tm 3.0 is a product of qualcomm technologies, inc.
