S-821BA Series www.ablic.com BATTERY PROTECTION IC FOR 1-CELL PACK © ABLIC Inc., 2024-2025 Rev.1.2_00 This IC is high-side protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy voltage detection circuit, delay circuit, and triple boost charge pump to drive an external charge / discharge FET. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. By using an external overcurrent detection resistor, this IC realizes high-accuracy overcurrent protection with less effect from temperature change.  Features ● High-accuracy voltage detection circuit Overcharge detection voltage: 3.500 V to 4.
