Abstract: An apparatus for wirelessly transmitting charging power is provided. The apparatus comprises a transmit coil configured to generate a wireless charging field for wirelessly transmitting charging power when driven by a current. The apparatus comprises a control circuit configured to cause the transmit coil to transmit a packet via the wireless charging field, wherein the packet comprises information indicative of the presence of the wireless charging field to cause a chargeable device to electrically disconnect a communication circuit from a receive coil within the chargeable device. The control circuit is further configured to cause the transmit coil to transmit the packet periodically based on a predetermined interval. The predetermined interval has a shorter duration than a duration of a communication interval of the communication circuit. The control circuit is further configured to reduce a magnitude of a strength of the wireless charging field during packet transmission.
