Description

IP5355 is a power management SOC. It integrates QC2.0/ QC3.0/SCP output fast charging protocol, FCP/ AFC input and output fast charging protocol, USB C/PD2.0/PD3.0 input and output protocol, USB C PD3.0 PPS output protocol, and BC1.2/Apple/ Samsung mobile phone charging protocol. It integrates the functions of synchronous up / down converter, lithium battery charging management, battery power indication, etc. to provide a complete power solution for fast charging mobile power bank. Any single USB port can support fast charging. When two or more output ports are used at the same time, only 5V is supported. Only one inductor is needed to realize the function of buck and boost, and only a few peripheral devices are needed in the application, which effectively reduces the size of the overall PCB and reduces the cost of BOM. The synchronous switch boost system of IP5355 can provide the maximum output capacity of 22.5W(10V@2.25A). When boost has no load, it will automatically enter the sleep mode. IP5355 charger provides 18W charging power and charging current up to 5.0A. Built in IC temperature, battery temperature and input voltage control loop, intelligent regulation of charging current. IP5355 supports 4LED battery level indicator. IP5355 supports lightning function and supports buttons. IP5355 supports I2C control interface
