An aerosol delivery device includes a housing enclosing a reservoir retaining an aerosol precursor composition. A first power-source terminal connects a power source to the aerosol delivery device. A heating element is configured to vaporize components of the aerosol precursor composition. A switch is coupled between the first power-source terminal and the heating element. A micro pump is arranged between the reservoir and the heating element to deliver aerosol precursor composition from the reservoir to the heating element. A driver circuit is coupled between the first power-source terminal and the micro pump, to drive the micro pump. A control component includes processing circuitry configured to switchably control the driver circuit to drive the micro pump, and switchably control the switch to connect the power source to the heating element and thereby power the heating element to vaporize components of the aerosol precursor composition.
