Abstract

See full text

An integrated circuit includes an integrated circuit interface, a wireless communications circuit, a selection circuit, and a control circuit. The integrated circuit interface includes a plurality of power supply input terminals, a plurality of power delivery terminals, and an energy harvest output terminal. The wireless communications circuit is configured to harvest energy received in a wireless communications signal and to provide harvested energy to the energy harvest output terminal. The selection circuit is coupled to the integrated circuit interface and is configured to selectively provide power to the plurality of power delivery terminals based on power received from the plurality of power supply input terminals in response to a control signal. The control circuit is configured to generate the control signal based on a first level of the harvested energy, any signals received on the plurality of power supply input terminals, and predetermined rules.
