Cxlb7404b/cxlb7404 is a USB mobile device charging interface control chip. In particular, it uses Qualcomm quick charge 2.0A class / B class specification to charge hvdcp adaptively

Cxlb7404b / cxlb7404 is a USB mobile device charging interface control chip. In particular, it uses Qualcomm quick charge 2.0A class / B class specification to charge hvdcp adaptively. Cxlb7404b / cxlb7404 can precisely adjust the output voltage of hvdcp according to the voltage request sent by the mobile device, thus saving up to 75% of the charging time. When the mobile device is plugged into the USB port, the cxlb7404b / cxlb7404 can automatically identify its type and make reasonable corresponding, so that the mobile device can always obtain the maximum current from the charging port. Cxlb7404b / cxlb7404 supports Apple iPad, Apple iPhone, Samsung Galaxy note, bc1.2 or YD / T 1591 compliant devices and almost all modern mobile devices. Cxlb7404b / cxlb7404 will automatically check whether the connected power receiving device is compatible with qc2.0 protocol specification before starting the output voltage adjustment. If it is detected that the power receiving device is not compatible with qc2.0 protocol, cxlb7404b / cxlb7404 will prohibit the output voltage adjustment, and only output at 5V voltage to ensure the safe operation of the old USB power receiving device
