Cxlb7494 is a power management SOC integrated with qc2.0 / 3.0 output fast charging protocol (compatible with DCP identification function, compatible with bc1.2 apple

Cxlb7494 is a power management SOC integrated with qc2.0 / 3.0 output fast charging protocol (compatible with DCP identification function, compatible with bc1.2, apple and Samsung phones), Synchronous Boost converter, lithium battery charging management, battery power indication and other functions, providing a complete power solution for mobile power supply. The high integration and rich functions of cxlb7494 only need one inductor to realize the function of voltage reduction and voltage rise, so that it only needs a few peripheral devices in application, and effectively reduces the size of the overall scheme and reduces the cost of BOM. The cxlb7494 synchronous switch boost system supports qc2.0 / 3.0 fast charging, provides the maximum output capacity of 15W, and the conversion efficiency is as high as 96%. When it is no-load, it will automatically enter the sleep state, and the static current will fall below 100ua. The synchronous switch charging system of cxlb7494 can provide up to 3A charging current and 97% charging efficiency. Built in IC temperature, battery temperature and input voltage control loop, intelligent regulation of charging current. The cxlb7494 has a built-in 14bit ADC, which can accurately measure battery voltage and current, and access ADC data through I2C. Cxlb7494 has built-in power calculation method, which can accurately obtain battery power information. The battery power curve can be customized to accurately display the battery power. Cxlb7494 supports 2 / 3 / 4 / 5 LED power display, intelligent identification of power display mode, support of lighting function, support of buttons
