How to choose lithium battery protection IC

Release time:2020/8/4 13:48:54

Lithium batteries are widely used. Mobile phones, tablets, mobile power supplies, electric toys, and smart wearables all need lithium batteries. In order to protect lithium batteries and make them last longer, they all need to use lithium battery protection ICs.

How to choose lithium battery protection IC, first from the brand.

The first-tier brands are of course Japanese, Seiko and Liguang. However, the supply of these two brands is insufficient and the prices are expensive. Therefore, only high-end manufacturers will choose, that is, if the quantity is large and the requirements are high, the agent will prepare the goods for you.

The second-tier brands are made in Taiwan, Hongkang Technology and Fujing. Fortune's DW01 series are widely used and cheap, but there are many fakes on the market, and basically 80% of them are substitutes produced by small workshops. Hongkang Technology started a little later, but it has his advantages. Hongkang's technology is separated from Jinggong, and the technical process is close to Jinggong's level, but the price is the same as that of Fujing, so the price is very high.

Third-tier brands are domestically produced. The domestically produced price is cheap, however. . . . I don't want to say more, lest I say that I am not patriotic.

Saifan Technology is the agent of Hongkang Technology's lithium battery protection IC, and some commonly used quantities are often available in large quantities.

The HY2110 series is the lowest-end one. It is used in low-end products such as mobile power supplies. The two most used ones are Hy2110-Cb and HY2110-DB.

The HY2113 series is a mid-to-high-end series. It is most widely used. Basically all products can be used. Those who pursue quality choose this series.

HY2113-FB2B, HY2113-CB1A, HY2113-NB4A and so on.

Hy2112 series is a special protection IC for lithium iron phosphate batteries. This is Hongkang's characteristic product, which is specially made for lithium iron phosphate batteries. The representative work is Hy2112-HB.

HY2120-CB is a masterpiece of dual-cell lithium battery protection IC, with very high cost performance.

HY2122 is a special protection IC for double-section lithium iron phosphate, the first choice for double-section lithium iron phosphate protection IC! Representative works are HY2122-BB1A, HY2122-AB1A.
