Abstract
The present disclosure relates to an electronic cigarette and an integrated circuit therefor. The integrated circuit incorporates a bi-directional control scheme for a charging process of a rechargeable battery and a discharging process of the rechargeable battery, and includes power devices used in both the processes. Thus, the integrated circuit has less semiconductor devices and lowered manufacturer cost. The integrated circuit has a temperature detection function for providing overheat protection of the system so that it operates in a safe temperature range. The integrated circuit also has a battery current-limiting function for limiting an output current of the rechargeable battery and protecting the same. The integrated circuit further has a short-circuit protection function for limiting an output current of the integrated circuit when the output current is too large and protecting the system.
