Abstract
Wireless power transfer between power transmitters and power receivers may be established by a digital ping phase during which the wireless power transmitter applies a power signal and waits for a valid response message from the power receiver. The response message may include an identification code and a checksum byte used by the power transmitter to validate the identification code. When a valid response is received, the power transmitter transitions to a power transfer phase.
