Recently, Songshan Lake IC Innovation Forum held successfully. More than 100 professionals and industry analysts gathered here who were from domestic well-known IC design companies. They discussed about the developments and opportunities of IC design industry.CellWise as the top provider of fuel gauge and won the Best Power IC Product of the Year Award and China Semiconductor Innovation Product and Technology Award several times which evaluated by EETIMES. CellWise was honored to be invited again to publish a new product which was the Fast Charge Management IC CW6113 at this summit.   CW6113 is a highly integrated battery charger management IC. CW6113 support 5A fast charge, integrated power path management with low impedance. The charge efficiency up to 93% when the charger current is 3A. CW6113 integrated 1.5A USB OTG output. Customers would set all product parameters through I2C interface. CW6113 keeps monitoring the battery Voltage, Current, temperature during the whole charging cycle to make it safe in charging and discharging. CW6113 is available in 32 pin, 4mm*4mm*0.75mm QFN package to improve the heat dispersion. It works with 0.69uH thin-small inductor to save PCB space that is a prefect fast charging solution for smartphone and mainly used for mobile devices such as Phones and Pads that require high-current fast charging.    In 2013, CellWise was invited to summit form firstly and published CW2015 which was a Li-ion battery fuel gauge. Took three years, CellWise became the world’s TOP 2 battery fuel gauge supplier with TI. In 2017, CellWise returned to Songshan Lake and published the industry-leading fast charging solution and made the smart terminals more convenient.Related media report, please click the link.https://mp.weixin.qq.com/s/bIQaIoIwqPZyGVO44YB7hQ

From Septemeber 26th-28th, The 22nd China Hardware fair was held at Yongkang International Convention and Exhibition Center. As the most well-known and influential industry event in China's hardware industry, which gather top tool enterprises from over the country.CellWise as a high-profile integrated circuits company was invited to participate in this exhibition.The exhibition area of Cellwise was being crowed in. The CellWise team explained the products in top spirits for each customer.Exhibitor of Cellwise Inside Cellwise built up quickly in the industry and recogonized by those well-known companies in just a few years. It is not only because of CellWise's well respected corporate culture but also because of the undoubted high quality of the products.CellWise brought all full line of electric tools products entered and was stationed in Yongkang International Convention and Exhibition Center.The exhibition was crowned with complete success.Finally, wish you happy national day, Autumn Festival, happy holidays.

CellWise CW6301 is a PMU that made for Smart Wearable Device. It won The 2016 China IoT Industry Technology Innovation Award. The awards were chosen by Electronic Fans Network and electronic and many fammous enterprises that are all the industry's authoritative technology portal media organization.On December 2,2016, 'The 3rd China IoT Conference 2016'  held in International Conference Center of KeXing Science and Technology Park, Nanshan Districk, Shenzhen.  There are 50 famous figures in the industry from the fammous enterprises such as Qualcomm, Huawei, Microsoft, NXP, Renesas, ST, Infineon, NI, ZTE, Cypress and Dialog attended the conference.CellWise CEO Bob.Jiang was invited to share 'Power Management Solution for Wearable Devices and IoT' on the smart wearable device forum and interview with the media.Mr.Jiang said that  'the core issue of the Wearable devices is the battery life, there's two methods to increase the standbly time  are increasing income and reducing expenditures.CellWise has successfully achieved these two points. The PMU CW6301 was the winning product has the features  as follow.Integrated four LDOs and high accuracy linear charger module, the Charge Termination Current is 1mA that has reached the highest international standard and made sure the battery is fully charged. Standby Comsumption is only 3.6μA witch guarantee equipment long standby time.Experts and media participating in the conference were interested in  and spoke highly of the products of CellWise.The products of CellWise have been applied to many  brands such Weloop, Xiaoqu, BYD, LongTengFei . The exhibition is Xiaoqu.

 The fifth episode of the second season of science and technology relativity'The Crimes and Punishments of Lithium Batteries'.[In addition to Li-ion Battery, do we have a better choice?] With so much talk about explosion of Samsung NOTE7 these days, althougth it remains unanswered, the problem must be related to battery. Are the batteries of phone  dangerous? Why don't you change another batteries? Is it develope hardly in battery market  without Li-ion battery?↙Click the link to watch the videohttp://www.iqiyi.com/v_19rr9g8p1s.html#vfrm=2-3-0-1&curid=543495100_35804b38cd79d0aef3ab749178749c7b

The 31st China International Hardware Fair was successfully held in the National Convention and Exhibition Center (Shanghai). The exhibition is technical and high specification. International and domestic electric industry leaders such as Bosch, Stanly, Makita, etc. all participated in this exhibition. In order to adapt to the development trend of li-ion battery electric tools, the exhibition specially launched the Li-ion battery electric tools symposium. As the only invited integrated circuit company in the industry, CellWise professionally explained the battery safety issues and solutions that everyone was concerned about.This keynote speech got great support from the leaders of the Power Tool Industry Association, especially Secretary-General Pan.Mr. Cao ,VP of CellWise, delivered welcome speech.CellWise invited Mr.Zhang who is electrochemical expert in the Li-ion battery industry. He shared with us the working principle, safety features and application notes of Li-ion batteries.Mr. Jiang, CEO of CellWise, introduced the products of CellWise for electric tools and shared the industry-leading one-stop solution for electric tools.Who participated in the conference had expressed interested in the products of CellWise and willingness to cooperate with CellWise.Integrated Solution for Electric Tools (Complete protection and High Cost-effective Solution).Complete protection solution: provide the overcharge, over discharge, over temperature protection, DC brushed motor controller, express current protection for single battery.High Cost-effective Solution: provide the overcharge protection and DC brushed motor controller and protection.
