Two-in-one li-ion 18650 battery protection chip and high-precision li-ion 18650 battery protection solution

　　No one doubts that 2012 will be a breakthrough year for smartphone shipments, and one of the major trends is becoming increasingly thinner and lighter. This is especially true for li-ion 18650 battery requirements for mobile phones. At this IICChina2012 exhibition, Fujing Electronics Co., Ltd. from Taiwan exhibited their latest solution: a two-in-one li-ion 18650 battery protection chip and a high-precision li-ion 18650 battery protection solution.

　　The traditional li-ion 18650 battery uses a protection IC plus a MOSFET. Since there are two components, it will inevitably occupy more PCB area. The two-in-one li-ion 18650 battery protection chip solution demonstrated by Fujing this time integrates the two on one chip, which can reduce the cost by 30% compared to the original one. It adopts DFN-5 package and the product thickness is only 0.6MM, which is significantly ahead of the industry. According to research reports, DFN packaging will be the fastest growing packaging mode in the next five years.

　　Fujing's li-ion 18650 battery protection solutions are mainly targeted at mid- to low-end customers. According to manager Huang Weilun, the total shipment volume in the entire mid- to low-end market is 120KK/month, while Fujing’s shipment volume has reached 50KK/month. In fact, the shipment volume of ICs with Fujing’s logo circulating in the market is At 100KK. It turns out that there are a lot of counterfeit products on the market. How to combat counterfeit goods has also become a matter of great concern to Fujing. However, this can also reflect the position of Fujing Electronics in the entire market.

　　Manager Huang also introduced high-precision battery protection solutions for high-end products. Japanese brands have always been in a very critical position in the semiconductor supply chain. After the March 11 earthquake last year, they once experienced supply difficulties. For long-term development considerations, Fujing Electronics has also begun to independently develop high-end products.

　　Asked about his views on the mobile phone market in 2012, Manager Huang said that in the future, the mobile phone market will gradually develop into two polarizations, taking a high-end route or developing in a cheaper direction. For Fujing, which has been targeting the mid- to low-end market, 2012 is a year of both opportunities and challenges.
