Abstract: A home appliance capable of minimizing a purchasing process for products required for the user or maintenance and repair of home appliances to allow a user to easily order the products at the appropriate time, and a control method of the home appliance. A home appliance comprises a user interface configured to display at least one immediate order icon purchasing a product immediately, and configured to receive a user's selection related to the displayed at least one immediate order icon, a controller configured to generate order information for ordering a product corresponding the selected immediate order icon, when the user's selection related to the at least one immediate order icon is input; and a communicator configured to transmit the generated order information to a sales server selling the product corresponding the selected immediate order icon.

Abstract: A cooling and heating control method of a multi type air conditioner in which a target pressure of a compressor is adjusted based on conditions of respective indoor units so as to reduce power consumption is provided. The cooling control method includes determining the indoor unit desired to execute power saving control, judging whether or not a difference between a temperature of a space in which the indoor unit desired to execute power saving control is located and a set temperature of the indoor unit is less than a reference value, raising a target evaporation temperature of the indoor unit upon judging that the difference is less than the reference value, comparing an evaporation temperature of the indoor unit with the raised target evaporation temperature, and raising an evaporation pressure of a compressor, when the evaporation temperature of the indoor unit is lower than the raised target evaporation temperature.

Abstract: The pad interface circuit includes a first stack MOS transistor having a first terminal connected to a pad and a bulk connected to a first supply voltage; a second stack MOS transistor having a first terminal connected to a second terminal of the first stack MOS transistor and a second terminal, a gate terminal, and a bulk that are connected to the first supply voltage; and a voltage level sensing circuit generating a feedback voltage by using a pad voltage applied from the pad. In addition, the feedback voltage is applied to a gate terminal of the first stack MOS transistor.

Abstract: An overvoltage protection circuit includes primary and secondary clamping circuits. The primary clamping circuit is configured to sink overvoltage current from a power supply voltage node (e.g., Vdd) to a reference voltage node (e.g., Vss) in response to an overvoltage condition at the power supply voltage node. The secondary clamping circuit, which is electrically coupled to an output of the primary clamping circuit, is configured to sink additional overvoltage current from the power supply voltage node to the reference node in response to detection of a overvoltage flag at the output of the primary clamping circuit. This overvoltage flag may be represented by a transition (e.g., low-to-high or high-to-low) of a signal generated at an output of the primary clamping circuit.
