CXCH76008支持快速充电2.0规范5V、9V、12V和20V输出电压支持QuickCharge QC2.0规范自动USB DCP短接D+至D线支持A级或B级的全部输出电压范围

CXCH76008设计用于支持QuickCharge QC 2.0（QC2.0）规范。它是一个支持QC2.0功能的低成本解决方案。CXCH76008集成了所有必要的功能，为标准适配器设计、便携式电池设计和汽车充电器设计添加了QC2.0功能。CXCH76008支持A级或B级的全部输出电压范围。可选地，可以禁止B级，以保护电池充电器免受意外损坏。在启用输出电压调整之前，CXCH76008会自动检测连接的电源设备（PD）是否支持QC2.0。如果检测到不符合QC2.0的PD，cxch76008将禁用输出电压调整，以确保仅使用传统的5v USB PDs的安全操作。

       CXCH76008 is designed to support QuickCharge QC 2.0 (QC2.0) specifications. It is a low-cost solution to support QC2.0 functions. CXCH76008 incorporates all necessary functions to add QC2.0 capability to standard Adaptor designs, Portable Battery designs, and Car-charger designs. CXCH76008 supports the full output voltage range of either Class A or Class B. Optionally Class B can be inhibited for protecting the battery charger from accidental damage. CXCH76008automatically detects whether a connected Powered Device (PD) is QC2.0 capable before enabling output voltage adjustment. If a PD that is not compliant to QC2.0 is detected the CXCH76008disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs.
