Electronic cigarette control chip and electronic cigarette

Abstract

The invention discloses an electronic cigarette control chip and an electronic cigarette. An internal oscillation and voltage reference module is started up when a working state control module detects that an SW terminal of the electronic cigarette control chip is started or the voltage of an OUT terminal is higher than the voltage of a VDD terminal of the electronic cigarette control chip, so that the electronic cigarette control chip starts to work; then, the working state control module detects whether the voltage of the OUT terminal is higher than the voltage of the VDD terminal, if yes, the electronic cigarette control chip is judged in the working mode, and if no, the electronic cigarette control chip is judged in the charging mode, so that different working states of the electronic cigarette control chip can be accurately detected, and the working modes are controlled according to the working states; and when the temperature of the electronic cigarette control chip is higher than the internally set temperature point, an immediate stop is required to prevent a lithium battery from over temperature.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette control chip and the electronic cigarette. Background technique [0002] E-cigarette is a new type of cigarette replacement product. It provides energy to the atomizer through the internal lithium battery, allowing the atomizer to heat the e-liquid (the e-liquid contains nicotine) to atomize the e-liquid. After inhaling the vape of electronic cigarettes, the user obtains nicotine similar to that in cigarettes, and at the same time avoids inhaling harmful substances such as tar and carbon monoxide produced after burning cigarettes. The electronic cigarette control chip can manage the charge and discharge of the lithium battery inside the electronic cigarette, drive the atomizer to heat, satisfy the smoking experience of the smoker, and ensure the health of the body. [0003] In current electronic cigarettes, the charging current of the contro...

AI Technical Summary

Problems solved by technology

[0003] In current electronic cigarettes, the charging current of the electronic cigarette control chip is often too low or the charging current is unstable, which causes the control chip to charge the lithium battery for a long time.

And because the discharge current of the electronic cigarette control chip is too low, the power to drive the atomizer is insufficient,
