Title:
WIRELESS CHARGING NOISE PROCESSING METHOD AND ELECTRONIC DEVICE SUPPORTING SAME
Document Type and Number:
WIPO Patent Application WO/2022/234955
Kind Code:
A1
Abstract:
Disclosed is an electronic device comprising a wireless charging circuit including a rectifier for converting AC power into DC power, a processor electrically connected to the wireless charging circuit, and a noise detection circuit connected between the wireless charging circuit and the processor, wherein the noise detection circuit includes: a comparator having an output terminal connected to a GPIO port of the processor; a first resistance element connected to an output terminal of the rectifier and configured to apply a portion of an output voltage of the rectifier to a first input terminal of the comparator; a second resistance element connected to the output terminal of the rectifier and configured to apply the other portion of the output voltage of the rectifier to a second input terminal of the comparator; and a capacitor connected between the second resistance element and the second input terminal. In addition, various embodiments identified through the present document are possible.
