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）
"Containing an IC in your battery?" A battery manufacturer asked us to develop a new IC for battery protection. It was in 1991, when Ni-Cd batteries had been widely used, Ni-MH batteries had appeared on the market, and in the same period of time Li-ion batteries had just come out in the market. The concept of "battery pack" had not been in common yet, so I was not able to have a clear picture of batteries including an IC.....Read More >
