Describes

This IC is used for secondary protection of lithium-ion rechargeable batteries, incorporating high-accuracy voltage detection circuits and delay circuits in a small 8-pin package.

Short-circuiting between cells makes it possible for serial connection of 3-cell to 5-cell.

By cascade connection of these ICs, it is possible to protect 6-serial or more cells lithium-ion rechargeable battery packs. 

Application

● Lithium-ion rechargeable battery pack
