CXCH76012是一款USB移动设备充电器接口芯片，它实现了高通公司针对自适应电压电池充电的快速充电3.0规范。它集成了所有必要的功能，为集成了电源开关IC（如InnoSwitch™、TinySwitch™、TOPSwitch™和其他采用传统二次侧反馈方案的充电器解决方案）的电路添加快速充电3.0功能。CXCH76012支持快速充电3.0的全部输出电压范围，包括从3.6 V到12 V（A级）的200 mV微步电压水平。CXCH76012提供了一套系统级保护功能，可在拔下适配器时保护电源和所连接的电源设备（PD）不受过度输出电压、二次侧热过载和错误电源传输的影响。此外，它还允许PD通过USB数据线远程关闭电源。在启用输出电压调整之前，CXCH76012会自动检测连接的PD是快速充电3.0还是快速充电2.0。如果检测到不符合Quick Charge 2.0或3.0的PD，CXCH76012将禁用输出电压调整，以确保仅限传统5 V USB PD的安全操作

产品概述 返回TOP
CXCH76012 is a USB mobile device charger interface IC which implements the Qualcomm’s Quick Charge 3.0 specification for adaptive voltage battery charging. It incorporates all necessary functions to add Quick Charge 3.0 capability to circuits incorporating Power Integrations’ switcher ICs such as InnoSwitch™, TinySwitch™, TOPSwitch™ and other charger solutions employing traditional secondary-side feedback schemes. CXCH76012 supports the full output voltage range of Quick Charge 3.0, including 200 mV microstepped voltage levels from 3.6 V to 12 V (Class A) . CXCH76012provides a suite of system level protection features protect- ing the power supply and connected Powered Device (PD) from excessive output voltages, sec- ondary side thermal overload, and faulty power delivery while adapter is unplugged.Additionally it allows the PD to remotely shutdown the power supply through USB data lines. CXCH76012automatically detects whether a connected PD is Quick Charge 3.0 or Quick Charge 2.0 capable before enabling output voltage adjustment. If a PD that is not compliant to Quick Charge 2.0 or 3.0 is detected, the CXCH76012disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs.
