Providing our analog technology
Our ICs achieve highly accurate and low supply current characteristics by CMOS analog technology. Small and highly accurate protection ICs facilitate your products to be safer than ever.
We have a wide lineup of battery protection ICs that include various protections such as Temperature Protection, Cell Balancing, Cascade Connection, Open-Wire Detection, and so on. Those protections are externally configurable, which makes the ICs meet the various needs of customers flexibly.
We have produced Li-ion battery protection ICs since the first appearance of Li-ion batteries in the mid-1990s.
We have a 17% global share*1 in the smartphone market, and large shipping records of each type of Li-ion battery protection ICs.(*1 According to internal investigation in 2018)
