S-8224A/B Series .ablic. © ABLIC Inc., 2017-2023 BATTERY PROTECTION IC FOR 2-SERIAL TO 4-SERIAL CELL PACK (SECONDARY PROTECTION) Rev.1.4_00 The S-8224A/B Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates high-accuracy voltage detection circuits and delay circuits. Short-circuits between cells acmodate series connection of two cells to four cells. The S-8224B Series limits its CO pin output voltage to 11.5 V max., so a FET with the gate withstand voltage of 12 V can be used. - Features - High-accuracy voltage detection circuit for each cell Overcharge detection voltage n (n = 1 to 4) 3.600 V to 4.700 V (50 mV step) Accuracy ±20...
