Qualcomm Quick Charge 3.0 solution companion to theIW1782要么IW1780H.

iw636是一个快速充电™用于USB接口的二级控制器支持高通量快速充电3.0技术和二次到主通信协议，适用于此IW1782要么IW1780H.primary-side AC/DC digital controller with to enable rapid charging of QC3.0/QC2.0-enabled mobile devices (MDs).

TheiW636集成了将命令的光耦合器驱动程序集成到IW1782要么IW1780H.AC/DC controllers. These chipsets provide efficiency as high as 90% to enable the higher power density needed for small form-factor fast charging adapters. It also uses Dialog'sSmartDefender™SMART HICCUP技术帮助在电缆和连接器中解决软短路。了解有关SmartDefender智能HICCUP技术的更多信息这里.

Qualcomm® Quick Charge™ is a product of Qualcomm Technologies, Inc.

Features

  • 支持Qualcomm®快速费用TM3.0 technology High Voltage Dedicated Charging Port (HVDCP) to provide VBUS从200mV增量3.6V到12V
  • Double-layer cable protection:
    • Secondary side (iW636）：专有的D + / D-过压保护（OVP）地址vBUSD+/Dsoft shorts
    • Primary side (IW1782要么IW1780H.）：SmartDefender™Smart HICcup技术在没有闩锁的情况下减少故障条件下的平均输出功率
  • 专有的二次到初级数字通信消除了初级侧的离散解码器，简化了系统设计
  • 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

Features
