CE8003 The working state is stable, non-smoking enters the saving mode, the static current is less than 5 uA; when smoking, the electric wire can exceed 7A, which can drive the electric wire with 0.8 Ω resistance; and the heating wire short circuit protection function, and also protects when the electric wire resistance is less than 0.6 Ω. The special integrated circuit internal optimization design, will not cause the crash phenomenon. Multimode (trickle, constant current, constant voltage) charging process, with superior charging performance, and battery protection function, protects the battery when the lithium battery voltage is<2.7V; When the battery voltage is charged to 2.7V, start the high current charging; When the battery voltage is close to 4.2V, the charging current decreases gradually, and enters the constant voltage until 4.2V charging stops; support multiple AC-DC and USB, and other charging equipment.
