We SII have various lineups of more advanced lithium-ion rechargeable battery Protection IC which are small, and have a high accuracy, the low current consumption.
Highly reliable due to the high-withstand CMOS process and the long history, these ICs are ICs suitable for lithium-ion rechargeable battery protection. We have various lineups such as for multi cells one to five, for secondary protection. Our lithium-ion rechargeable battery protection ICs satisfy customer's request and strongly support the new product design.
The protection ICs for 1 cell is suitable for making mobile phones and smartphones smaller and lighter. For the ICs, small package SNT-6A (1.6×1.8×0.5mm) is used, and they have a high-accuracy voltage detection circuit and a delay circuit. They are suitable for battery pack for mobile phone because the necessary external parts to be set will be fewer.
The ICs for 2 cells are suitable for various applications such as video cameras and digital cameras.
The ICs for 3 cells can be used for applications which use the large power supply voltage such as notebook PC.
Moreover, we have various lineups for 5 cells, switch to 3 cells/4 cells, for second protection, for voltage monitoring.

Since 1990's, lithium-ion batteries have been used in various portable devices.
We SII has been designing and developing the lithium-ion battery protection ICs from then.
Since 1993, we have started designing general-purpose ICs, and also many ICs for various cells and for second protection are used in the industry.
Our long history for 18 years strongly assures the customer's product development.
