IP5353_I2C_AABC_DWDKO

This chip integrates QC2.0/QC3.0/SCP output fast charging protocols, FCP/AFC input/output fast charging protocols, TYPE-C/PD2.0/PD3.0 input/output protocols, PPS output protocol, and BC1.2/Apple/Samsung DCP protocols. It also integrates a synchronous buck-boost converter, battery charging management, battery fuel gauge, and other multi-function power management SOC, providing a complete power solution for fast-charging power banks. It supports simultaneous multi-port USB output, up to 4 USB ports with fast charging, and any single USB port supports fast charging independently. In multi-port output and pass-through charging mode, only the 5V voltage level is supported. Thanks to its high integration and rich feature set, minimal external components are required — a single inductor enables both buck and boost functionality, effectively reducing solution size and BOM cost. The synchronous switching boost system delivers up to 22.5W (10V@2.25A) output capability. Under light load, the chip automatically enters sleep mode. The synchronous switching charging system supports 18W charging with battery-side charging current up to 5.0A. Built-in chip temperature, battery temperature, and input voltage control loops enable intelligent charging current regulation. Built-in TYPE-C & PD2.0/PD3.0 protocol support. Supports 4-LED battery level display, lighting function, button function, and I2C control interface.
