Please answer professionalsWhy is there a big difference in the price of the mobile power panel?What does "double charge and over release" software and hardware mean?The composition of each component of PCBA and the function of each component
The circuit of the mobile power supply is divided into three parts, charging control, step-up control, and battery protection. There are two kinds of hardware boards and software boards. The so-called hardware board is directly completed by IC itself, so the function does not require circuit designers to do functional design. The relative quality of the mobile power supply is relatively stable. The software board is to use the above three parts of discrete components, plus microcontroller, through the design and development of software written to achieve control, protection and work. Such mobile power supply is relatively cheap, because of the designer's level of difference, stability is not good, but functional design is more flexible, more functional than the hardware board.
What does "double charge and over release" software and hardware mean? The so-called hardware protection is designed by the IC itself to protect the plant, compared to over-voltage, over-current, temperature protection, etc., no product designers need to use software to detect design protection function. Soft protection is the design of circuit developers using software test results and set the protection function.
Why is there a big difference in the price of the mobile power panel? Because of the protection of IC brand is not the same, the performance is also very different, and what brand of brand-name things of large price differences.
1. mobile power PCBA: refers to the printed circuit board in mobile power supply.2. the circuit board is designed by the electronic engineer, the battery protection board, the step-up circuit, charging management and peripheral components (such as resistors, capacitors, diodes, etc.) and printed circuit boards.
