This scheme uses high-performance 8-bit MCU to achieve a cost-effective small cigarette e-cigarette solution. The main chip is integrated with an ultra-high precision ADC module, and the lithium battery charging module is integrated inside. The circuit design of the whole scheme is relatively simple, the peripheral devices are less, and the overall hardware cost has a strong advantage.
Scheme features:
1) Sensitive air flow induction, instant preheating.
2) High-precision AD combined with PID algorithm to achieve constant power control and ensure taste.
3) Intelligent tobacco control system, effectively prevent excessive smoking.
4) Standby power consumption below 5uA.
5) Adequate protection mechanism: overheat protection, overcharge protection, short-circuit open circuit protection, etc.
