BATTERY PROTECTION IC
FOR 2-SERIAL-CELL PACK
Rev.3.9
_00
The S-8252 Series is a protection IC for 2-serial-cell lithium-ion / lithium polymer rechargeable batteries and includes high-
accuracy voltage detection circuits and delay circuits.
The S-8252 Series is suitable for protecting 2-serial-cell rechargeable lithium-ion / lithium polymer battery packs from
overcharge, overdischarge, and overcurrent.
