S-8253B Overview
Rev.2.1_00 BATTERY PROTECTION IC FOR 2-SERIAL OR 3-SERIAL-CELL PACK S-8253A/B Series The S-8253A/B Series are protection ICs for 2-serial or 3-serial cell lithium-ion rechargeable batteries and include high-accuracy voltage detectors and delay circuits. These ICs are suitable for protecting lithium-ion battery packs from overcharge, overdischarge and overcurrent.
S-8253B Key Features
