  • Apparatus and methods for enhanced operation in a wireless charging receiver
    Patent number: 11949243
    Abstract: A method implemented by a wireless charging receiver (RX) includes detecting, by the wireless charging RX, that a voltage potential of an output of a rectifier of the wireless charging RX has met a boost mode threshold; placing, by the wireless charging RX, the rectifier into a boost mode; and detecting, by the wireless charging RX, that the voltage potential of the output of the rectifier of the wireless charging RX has met a specified threshold, and based thereon, negotiating, by the wireless charging RX with a wireless charging transmitter (TX), to initiate a power transfer.

  • Methods and apparatus for protecting wireless charging receivers
    Patent number: 11404920
    Abstract: A wireless charging receiver includes a controller configured to determine that a first overvoltage threshold is met and based thereon enable a first switch to couple an output of a rectifier to electrical ground through a first resistor, to determine that a second overvoltage threshold is met and based thereon enable receive resonant circuit switches to short circuit a receive resonant circuit, to determine that a hysteresis threshold is met and based thereon disable the receive resonant circuit switches to open circuit the receive resonant circuit, and to determine that a hysteresis cycle threshold is met and that the receive resonant circuit switches are disabled and based thereon enable the second switch to couple the second resistor to the electrical ground and to communicate to wireless charging transmitter to decrease the power level on wireless charging receiver side.
