BATTERY PROTECTION IC
FOR 2-SERIES OR 3-SERIES-CELL PACK
Rev.2.5
_00
The S-8253C/D Series is a protection ICs for 2-series or 3-series cell lithium-ion rechargeable battery and includes high-
accuracy voltage detector and delay circuit.
This IC is suitable for protecting lithium-ion battery packs from overcharge, overdischarge and overcurrent.
