CE8002 is a PWM constant voltage output with charging function e-cigarette drive ASIC, using SOT 23-6 package, with ultra-low energy consumption, completely solve the original MCU control scheme crash phenomenon. The chip uses air pressure sensor to detect the user's smoking action to avoid accidental triggering phenomenon. The output voltage of the heating wire output port can be adjusted according to the application requirements to achieve different smoke flavors and optimize the taste. The output voltage is constant with minimal fluctuations. The LED output port can drive an LED light as the signal light of the e-cigarette for visual interaction with the user. When smoking, LED lamp automatically simulates the phenomenon of fire flashing when ordinary tobacco is burning, and adopts the design of gradually brightening and fading to make the fire effect more realistic. When not smoking, the LED light reminds the user of the different working state of the chip through different flashing or long lighting methods.
