Protection board market capacity
Global market capacity is around 100KK/M
1) Level A market (40KK /M)
Note: The main manufacturers of protection ICs in Tier A market are Seiko, Ricoh, Midea, Hongkang HYCON;
The main manufacturers are Sanyo, AO ;,
Seiko quality The best, Hongkang has the best value for money. ?
For example, the overload detection voltage accuracy of Hongkang two-cell lithium battery protection IC reaches 0.025V, which is already quite high.
2) Level B Market (40KK/M)
Note: Major manufacturers of protection ICs in Level B market include Fujing, Xinde and Vimicro; of MOSFET There are Sanhewei, Huarui, Nanhai, Xuanchang and Maoda;
3) C-level market (20KK/M)
Note: the main manufacturers of protection integrated circuits in Le C-level market There are Shilan, Black Forest and Jinweike;
Major MOSFET manufacturers include Zhuhai Nanke, Black Forest and Jinweike;?
I think that you You should look for a lithium battery protection IC manufacturer.
Front-line manufacturers include Japan's Seiko and Liguang, as well as Taiwan's Hongkang HYCON and Fujing.
The second level includes Fuman, BYD Micro, Zhongying, etc. locally produced.
Personally, I recommend products made in Taiwan, which are more cost-effective. If you only want low-end products, you can choose domestic products.
We are specialized in this type of protection IC.
