CE8004 The working state is stable, non-smoking into the power saving mode, the static current is less than 5 uA; when smoking, the electric wire works, the current can exceed 7A, can drive the electric wire of 0.8 Ω resistance; and the heating wire short circuit protection function, and will protect when the electric heating wire resistance is less than 0.6 Ω. The special integrated circuit internal optimization design, will not cause the crash phenomenon. It has multi-mode flow (trickle current, constant current, constant voltage) charging process, with superior charging performance and battery protection function, which can protect the battery when the lithium battery voltage is<2.7V. When the battery voltage is charged to 2.7V, the high current charging starts; when the battery voltage is near 4.2V, the charging current will gradually decrease and enter the constant voltage until 4.2V. The charging stops. Multiple charging devices such as AC-DC and USB are supported. CE8004 Has a variety of protection functions: long time smoking (10 seconds) protection, overtemperature protection, underpressure protection, etc. At the same time, it also has the function of multiple single LED display. According to different working modes, there are different LED instructions in circuit starting, smoking time, voltage detection, various protection and charging process. Peripheral application circuit is simple. The IC is integrated with voltage regulator tube and power tube, with low standby power consumption; the peripheral device only need 1 LED, lamp and a capacitor, can also connect to the fingerprint module, the whole machine input cost is low.
