summary
The Panasonic Wireless Power Control IC supports all devices (DSC, DVC, Walkman, mobile phone, smartphone, etc.) and is compliant with the WPC 1.1 (Qi standard) of the WPC (Wireless Charging Alliance). The Panasonic wireless power solution uses a transmitter control IC (NN32251A) for power transmitters (battery chargers) and a receiver control IC (AN32258A) for power receivers (devices) to control power transmission.
