Abstract
An electronic device according to various embodiments may include: a hall integrated circuit (IC) configured to detect magnetic flux generated by an external device enclosing at least a portion of the electronic device; a wireless charging circuit; and at least one processor configured to be connected to the hall IC and the wireless charging circuit, wherein the at least one processor is configured to: receive an output value for the detected magnetic flux from the hall IC; and control the wireless charging circuit, based on the output value.
Claims19
An electronic device comprising:
- a hall integrated circuit (IC) configured to detect magnetic flux generated by an external device enclosing at least a portion of the electronic device;
- a wireless charging circuit;
- and
- at least one processor configured to be connected to the hall IC and the wireless charging circuit,
- wherein the at least one processor is configured to:
- receive an output value for the detected magnetic flux from the hall IC;
- and
- control the wireless charging circuit, based on the output value,
- wherein the magnetic flux detected by the hall IC is in a first direction when a lid of the external device is closed and is in a second direction opposite the first direction when the lid of the external device is folded backwards.
An operating method of an electronic device, the method comprising:
- detecting, by a hall integrated circuit (IC) of the electronic device, magnetic flux generated by an external device enclosing at least a portion of the electronic device;
- receiving, by at least one processor of the electronic device, an output value for the detected magnetic flux from the hall IC;
- and
- controlling, by the at least one processor, a wireless charging circuit of the electronic device, based on the output value,
- wherein the magnetic flux detected by the hall IC is in a first direction when a lid of the external device is closed and is in a second direction opposite the first direction when the lid of the external device is folded backwards.
An electronic device comprising:
- a sensor configured to obtain a first signal corresponding to an external device enclosing at least a portion of the electronic device;
- a wireless charging circuit;
- and
- at least one processor,
- wherein the at least one processor is configured to:
- obtain the first signal from the sensor;
- and
- if the first signal satisfies a predetermined condition, prevent the electronic device from being charged using the wireless charging circuit,
- wherein the first signal detected by the sensor is in a first direction when a lid of the external device is closed and is in a second direction opposite the first direction when the lid of the external device is folded backwards.
