The working principle of electronic cigarettes is to heat the e-liquid in the atomizer through battery power, generating nicotine vapor for users to inhale. This process avoids the harmful substances produced by traditional cigarette combustion, but the safety of electronic cigarettes still needs further scientific research and verification. Driven by the increasing regulatory laws in various regions, the design of electronic cigarette products is moving towards intelligence and safety. Ruiyang Xin Electric provides a wide range of simulation products, including lithium battery charging ICs, LDOs, gate drivers, comparators, current detection amplifiers, etc., to achieve functions such as lithium battery charging, system power supply, power switch driving, signal conditioning, and current detection, providing users with a one-stop simulation solution.
