Abstract: A wireless power receiver includes circuitry configured to receive a wirelessly induced voltage from a wireless power transmitter via a magnetically induced connection with the wireless power transmitter. It is determined that an overvoltage condition exists when the wirelessly induced voltage exceeds a threshold voltage, and the wirelessly induced voltage is reduced in response to determining that the overvoltage condition exists. The circuitry communicates the overvoltage condition to the wireless power transmitter via the magnetically induced connection while over-voltage protection is enabled.

Abstract: An integrated circuit is provided. The integrated circuit includes a mapping circuit configured to determine a state associated with a first universal series bus (USB) communication mode based on one or both of a signal level on a first data line and a signal level on a second data line. The integrated circuit also includes a line state converter circuit configured to generate a line state associated with a second USB communication mode based on the determined state and based on one or both of the signal level on the first data line and the signal level on the second data line.
