CXLB74222 is a USB mobile device charging interface IC, which uses Qualcomm Quick Charge 3.0 specification to Charge the battery with adaptive voltage. It integrates all necessary functions and can add QC 3.0 functions to the circuit shown in the application diagram or other charger solutions using traditional secondary feedback. Supports the entire output voltage range of QC3.0 with a voltage step of 200mV/gear. If the output voltage range is 3.6V to 12V, it is Class A, and if the maximum output voltage reaches 20V, it is class B. It can automatically detect whether the connected power receiving equipment is compatible with QC 3.0 or QC 2.0 protocol before the output voltage adjustment is enabled. If it is detected that the powered device is not compatible with QC 2.0 or 3.0 protocol, the output voltage adjustment will be prohibited, and the output voltage will only be 5V to ensure that the old USB powered device can work safely.
