Chip solution Battery power management chip IP5328P (C188809)Welding method is used for the battery port, and the pad is increased to ensure excessive current.Lithium battery protection uses Seiko S8261, 3.08v threshold protection chip.mos selects IRF7831 low internal resistance.2 USB A port output1 USB B port input1 USB C port input/outputAny port supports fast chargingThe battery charging current can reach up to 5.0AAdaptive charging current adjustmentSupport 4.20V, 4.35V, 4.40V, 4.50V batteries (resistance configuration)IP5328P is an integrated QC2.0 / QC3.0 output fast charging protocol, FCP/AFC/SFCP input and output fast charging protocol, MTK PE+ 1.1&2.0 output fast charging protocol,USB C/PD2.0/PD3.0 input and output protocol, USB CPD3.0 PPS output protocol, compatible with BC1.2/Apple/Samsung mobile phone, synchronous step-up/step-down converter,Lithium battery charge management, battery power indication and other multi-functional power management SOCs provide a complete power solution for fast charging mobile power.It can support four USB ports of USB A x2, USB B, and USB C at the same time. Any single USB port can support fast charging. When two or more output ports are used at the same time, only 5V is supported.The high integration and rich functions of IP5328P require only one inductor to realize the step-down and step-up functions. In application, only a few peripheral devices are needed, which effectively reduces the size of the overall solution and reduces the BOM cost.The IP5328P's synchronous switching boost system can provide a maximum output capacity of 18W. Even if the battery voltage is low, the output of 18W can still maintain more than 90% efficiency. When no load, it will automatically enter the sleep state.IP5328P's synchronous switch charging system provides charging current up to 5.0A. Built-in IC temperature, battery temperature and input voltage control loop to intelligently adjust the charging current.IP5328P has built-in USB C&PD2.0/PD3.0 protocol.IP5328P has a built-in 14bit ADC, which can accurately measure the battery voltage and current, and can access the ADC data through I2C. IP5328P has a built-in power calculation method to accurately obtain battery power information. The battery power curve can be customized to accurately display the battery power.IP5328P supports 1/2/3/4 LED power display, intelligent identification of power display mode; supports lighting function; supports buttons. Customizable functions: while charging and discharging, PD15V output, charging wearable devices and other functions.?
