Abstract
An aerosol delivery device is provided that includes a cartridge coupled with a control body. The cartridge is equipped with a heating element, an authentication device and a second switching circuit. The control body includes a first switching circuit and is configured to exchange authentication signals with the authentication device to authenticate the cartridge for use with the control body and, only in instances in which the cartridge is authenticated, direct power to the heating element. The control body and the cartridge include respectively a two-wire electrical connector and a corresponding two-wire electrical connector coupled with one another, and across which the authentication signals are exchanged and the power is directed. The first switching circuit is coupled with the second switching circuit to form switching circuitry configured to manage the authentication signals and the power across the two-wire electrical connector.
