Abstract
An integrated circuit (IC) for use in a device includes a wireless power receiver circuit, a transceiver, and a processing module. The wireless power receiver circuit is operable to convert an electromagnetic signal into a voltage. The transceiver, when operable, transceives a control channel communication. The processing module is operable to: transition the device from an idle state to a charge state when a wireless power transmitter unit is detected; transition the device from the idle state to a wireless power operated state when a wireless power transmit circuit is detected and the device is enabled; and transition the device from the idle state to a battery operated state when the device is enabled and the wireless power transmit circuit is not detected.
