L PACK Rev.1.4_00 The S-8245B/D Series is a protection IC for 3-serial to 5-serial cell lithium-ion rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 3-serial to 5-serial cell lithium-ion rechargeable battery packs from overcharge, overdischarge, and overcurrent. Connecting an NTC, it allows for the temperature detection at four different points: high temperature detection during charging, low temperature detection during charging, high temperature detection during discharging, and low temperature detection during discharging.
