Abstract:
Power distribution circuitry to improve wireless power distribution and facilitate wireless power transfer (WPT) operations in a wireless communication device under a variety of operating conditions. In various exemplary embodiments of the disclosure, the power distribution circuitry operates to provide a wireless power (WP) supply voltage to wireless communication circuitry of the device in order enable a WPT connection procedure under certain low power conditions. Such conditions might include a power off mode, a sleep mode, and dead/low battery operating conditions wherein the available battery supply voltage is less than a threshold voltage required to enable device components. The power distribution circuitry may switch the supply voltage of the wireless communication circuitry to another available supply voltage source after the WPT connection procedure is completed and wireless power is being received by the wireless communication device.
