描述 Description

The FS3332 Series are protection ICs for 2-serial-cell lithium-ion/lithium-polymer rechargeable batteries and include high-accuracy voltage detectors and delay circuits. These ICs are suitable for protecting 2-cell rechargeable lithium-ion/lithium-polymer battery packs from overcharge, overdischarge, and over-current.
