Abstract
A dual mode wireless power receiver (DMWPR) selectively applying a received power to a load device and utilizing at least a part of the power to power-up, communicate, and charge a secondary wireless power receiver (SWPR) is provided. The DMWPR includes a first circuitry having an impedance network, a switch network, a filter capacitor, and one or more switches, and a second circuitry having a security engine, a control logic circuit, and a modulator/demodulator circuit. The first circuitry receives power in charging mode and transmits power in communication mode. The second circuitry configures the first circuitry to allow receipt and transmission of power, receives and interprets data from SWPR in the identified wireless power protocol, and based on the type of SWPR authenticates, decrypts, and encrypts data transfer between DMWPR and SWPR, and receives and executes on a request from SWPR to perform a function associated with transmitted power.
