Claim 0:
1. A device that is operative to transfer power wirelessly, the device comprising:
a drive-sense circuit (DSC) operably coupled to receive a reference signal and to generate a drive signal based on the reference signal, wherein, when enabled, the DSC operably coupled and configured to:
provide the drive signal to a first coil via a single line and via a resonating capacitor and simultaneously to sense the drive signal via the single line, wherein the first coil is implemented to transfer power wirelessly to a second coil of another device, wherein sensing of the drive signal via the single line includes detection of one or more electrical characteristics of the drive signal; and
generate a digital signal representative of the one or more electrical characteristics of the drive signal based on an error signal corresponding to a difference between the drive signal and the reference signal, wherein the one or more electrical characteristics of the drive signal includes information regarding whether the another device is within proximity to the device and is suitable for receiving power wirelessly from the device.
