AN-1027 SLG55546 Port Power Management

Port Power Management (PPM) system based on SLG55546 is used when more than one USB charging port exists in the system. To prevent overload of the single internal 5V VBUS power source when multiple USB ports are simultaneously providing high charging current, PPM is a feature that allows high current charging in one port, and forces other USB ports to a lower current limit.
