Intelligent distribution of current is actually not a very fresh concept. As Apple began to push the iPad, it began to give the charging device a different charging current demand. So semiconductor manufacturers that produce power control chips have proposed a process of negotiating current—the power management IC of the mobile device and the charger power management IC exchange information, identify the devices that need to be charged, and finally agree on the supply current.
In general, the power management IC in mobile devices is designed to be used only with the original charger, so there is no need to adapt the charger, so the charger will have the need to identify different devices. . The charger's power management IC is a complete solution consisting of multiple chips with different functions. It usually has a power supply PWM master IC, a rectifier MOSFET and a master IC, as well as a USB-side analog IC, and a capacitor for filtering. Wait. With so many members, which one really involves intelligent distribution? Or are they all inserting a hand inside?
