Circuitry to reduce residual voltage of electronic component and electronic device comprising same

A method of operating an electronic device, wherein the electronic device comprises an electronic component, comprising circuitry, a thermistor, and a switch configured to control an electric connection associated with the thermistor, the method comprising:

• receiving an input to deactivate the electronic device;
• controlling, based on the input, the switch such that a power signal transmitted to the electronic component is transmitted to the thermistor;
• and
• controlling, while the power signal is transmitted to the thermistor, the switch such that a voltage of the power signal transmitted to the thermistor is maintained to be lower than or equal to a reference voltage.

An electronic device comprising:

• power circuitry;
• an electronic component comprising circuitry;
• a thermistor, wherein a resistance of the thermistor is configured to increase by a temperature of the thermistor being increased;
• a switch configured to connect the thermistor to a node, wherein the node is included in a power path to transmit a power signal from the power circuitry to the electronic component;
• and
• control circuitry configured to control the switch,
• wherein the control circuitry is configured to:
• in a first state to activate the electronic component, control the switch such that the thermistor is electrically disconnected from the power path;
• and
• in a second state different from the first state, control the switch such that a voltage of the thermistor is maintained to be lower than or equal to a reference voltage.
