Hair Dryer PCBA

Craftsmanship：BLDC motor is used to control the motor work. NTC detects the temperature and precisely controls overcharge and undervoltage.

Advantages：0V charging, precise control of small charging current to ensure that the battery will not be damaged by high current charging in the low voltage area.

Solutions：Precise control of PWM duty cycle control MOS on/off, reduce MOS temperature rise, ensure MOS long-term work.   

Design Advantages：Product work multiple safety protection, precise control of motor work protection current, working temperature high / low temperature protection, under voltage over voltage protection, battery open circuit, short circuit protection.

Solutions：Design a variety of detection circuits to make the product safer and longer life in work.
