3 Description
IP6821 is a highly integrated, WPCqi
compliant wireless charging transmitter control
chip. The chip internally integrates H-bridgedrivermodule, ASK communication demodulationmodule, adapter fast charging Sink protocol andother necessary wireless charging resources.
IP6821 supports customisation of protocols,
foreign object detection sensitivity, indicator lightsand other functions.
IP6821 adopts SOP16 package, PINpinfunction layout is optimised for wireless chargingapplication, which is very convenient for PCBdrawing.
