1. An aerosol delivery device comprising:
a housing structured to retain an aerosol precursor composition;
a sensor configured to produce a measurement of pressure caused by airflow through at least a portion of the housing, and convert the measurement of pressure to a corresponding electrical signal;
a first terminal and a second terminal configured to connect a power source to the aerosol delivery device;
a control component including:
a processor configured to receive the corresponding electrical signal and in response connect the power source to a load to cause the aerosol delivery device to produce an aerosol from the aerosol precursor composition;
a high-side load switch between the sensor and the load, the high-side load switch controllable by the processor to connect and disconnect the power source to and from the load;
a near-field communication (NFC) tag coupled to the processor and configured to enable the aerosol delivery device to establish NFC communication with a computing device equipped with a NFC reader; and
a second high-side load switch between the first terminal and the NFC tag, the second high-side load switch controllable by the processor to connect and disconnect the power source to and from the NFC tag, and limit input current to the NFC tag; and
a voltage regulator coupled to and between the sensor and the first terminal, the voltage regulator configured to step down voltage from the power source to the sensor and thereby power the sensor,
wherein the processor is configured to control the high-side load switch to connect the power source to the load only when the power source is disconnected from the NFC tag.
