DW01A Lithium Battery Protection IC | SOT23-6 Single-Cell Li-ion Protection

The DW01A is a highly reliable single-cell lithium-ion/lithium-polymer battery protection IC designed to safeguard battery packs from damage caused by overcharge, over-discharge, overcurrent, and short circuit conditions. Widely used in mobile devices, battery-powered electronics, and Li-ion protection boards, the DW01A ensures safe charging and discharging to extend battery lifespan.

With built-in high-precision detection circuits and extremely low quiescent current, the DW01A provides stable and efficient protection while minimizing energy loss. Its compact SOT23-6 package makes it ideal for integration directly within small battery packs and space-limited protection modules.
