Touch circuit for preventing erroneous touch due to temperature change, electronic device comprising touch circuit, and method for operating same

An electronic device comprising:

• a temperature sensor configured to sense temperature information of the electronic device;
• a processor;
• and
• a touch circuit, wherein the touch circuit is configured to:
• identify that the temperature information sensed by the temperature sensor is lower than or equal to a designated threshold temperature,
• identify whether values included in a designated number of frames of touch sensing information are within a designated range based on the temperature information being lower than or equal to the designated threshold temperature, each frame of the touch sensing information including a plurality of values each corresponding to one of a plurality of nodes of the touch circuit,
• refrain from outputting, to the processor, touch information associated with at least one first node having a value within the designated range among the plurality of nodes, based on a result of identifying whether the values included in the designated number of frames of touch sensing information are within the designated range, and
• output, to the processor, touch information associated with at least one second node having a value outside the designated range among the plurality of nodes, based on the result of identifying whether the values included in the designated number of frames of touch sensing information are within the designated range.
