S-8240A Series www.ablic.com BATTERY PROTECTION IC FOR 1-CELL PACK ABLIC Inc., 2015-2020 Rev.3.2 00 The S-8240A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy voltage detection circuits and delay circuits. The S-8240A Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. Features High-accuracy voltage detection circuit Overcharge detection voltage 3.500 V to 4.600 V (5 mV step) Accuracy 20 mV *1 Overcharge release voltage 3.100 V to 4.600 V Accuracy 50 mV Overdischarge detection voltage 2.000 V to 3.400 V (10 mV step) Accuracy 50 mV *2 Overdischarge release voltage 2.000 V to 3.400 V Accuracy 100 mV Discharge overcurrent detection voltage 0.015 V to 0.200 V (5 mV step) Accuracy 5 mV *3 Load short-circuiting detection voltage 0.065 V to 0.500 V (25 mV step) Accuracy 40 mV Charge overcurrent detection voltage 0.200 V to 0.015 V (5 mV step) Accuracy 5 mV Detection delay times are generated only by an internal circuit (external capacitors are unnecessary). 0 V battery charge: Enabled, inhibited Power-down function: Available, unavailable Release condition of discharge overcurrent status: Load disconnection, charger connection Release voltage of discharge overcurrent status: VRIOV, VDIOV High-withstand voltage: VM pin and CO pin: Absolute maximum rating 28 V Wide operation temperature range: Ta = 40C to +85C Low current consumption During operation: 1.5 A typ., 3.0 A max. (Ta = +25C) During power-down: 50 nA max. (Ta = +25C) During overdischarge: 500 nA max. (Ta = +25C) Lead-free (Sn 100%), halogen-free *1. Overcharge release voltage = Overcharge detection voltage Overcharge hysteresis voltage (Overcharge hysteresis voltage can be selected from a range of 0 V to 0.4 V in 50 mV step.) *2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage (Overdischarge hysteresis voltage can be selected from a range of 0 V to 0.7 V in 100 mV step.) *3. Load short-circuiting detection voltage = Discharge overcurrent detection voltage + 0.025 n (n can be selected from any integer value greater or equal to 2) Applications Lithium-ion rechargeable battery pack Lithium polymer rechargeable battery pack Packages SOT-23-6 SNT-6A HSNT-6(1212) 1 BATTERY PROTECTION IC FOR 1-CELL PACK S-8240A Series Rev.3.2 00 Block Diagram VDD Overdischarge detection comparator DO Overcharge detection comparator Discharge overcurrent detection comparator VSS Control logic Delay circuit Load short-circuiting Oscillator detection comparator Charge overcurrent detection comparator VM CO Figure 1 2
