Control component for segmented heating in an aerosol delivery device

An aerosol delivery device comprising:

• a housing structured to retain an aerosol precursor composition;
• a segmented heater including a plurality of heating elements that are separately powerable to heat and thereby vaporize components of the aerosol precursor composition;
• a control component coupled to and configured to separately, controllably power the plurality of heating elements of the segmented heater, the control component including:
• a logic circuit coupled to the segmented heater, the logic circuit being a demultiplexer or a latched serial-in parallel-out (SIPO) shift register, and including a data input and a plurality of outputs each output of which is coupled to a respective one of the plurality of heating elements of the segmented heater;
• and
• a processor configured to produce a logic signal as a waveform that switches between a high voltage level and a low voltage level that represent respectively a first value and a second value, the processor being coupled and configured to provide the logic signal including at least the first value to the data input of the logic circuit and cause the logic circuit to provide the first value and thereby the high voltage level at one or more outputs of the plurality of outputs of the logic circuit, and thereby power respective one or more heating elements of the plurality of heating elements of the segmented heater to heat and thereby vaporize components of the aerosol precursor composition, any other heating elements of the plurality of heating elements being simultaneously unpowered;
• and
• a plurality of sense resistors, each connected between a corresponding output of the plurality of outputs of the logic circuit and the respective one of the plurality of heating elements, the sense resistors configured to measure voltage or current from the outputs of the logic circuit directed to each of the plurality of heating elements, and to enable a safety feature of the control component to control power to the heating elements, based on the measured voltage or current indicating a surge in the voltage or the current output by the logic circuit, to prevent damage to the heating elements of the aerosol delivery device.
