After founded in 2000, we succeeded in mass-producing POC(Protection One Chip) for the first time in the world, a key component of the protection circuit for secondary battery in 2005.
In 2012, we developed PMP(Protection Module Package) that combines IC, FET, and passive components into a single package, and became the world's only one manufacturer.
We secured domestic and overseas' major mobile phone makers as customers with this technology, and became the No.1 in global market share in the field of protection circuit for secondary battery.
