ABLIC S-8242BAH-T8T1G

The S-8242B Series are protection ICs for 2-serial-cell lithium-ion/lithium polymer rechargeable batteries and include highaccuracy voltage detectors and delay circuits. These ICs are suitable for protecting 2-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.

• High-accuracy voltage detection for each cell
  • Overcharge detection voltage n (n = 1, 2): 3.9 V to 4.5 V (50 mV steps), Accuracy ±25 mV
  • Overcharge release voltage n (n = 1, 2): 3.8 V to 4.5 V, Accuracy ±50 mV
  • Overdischarge detection voltage n (n = 1, 2): 2.0 V to 3.0 V (100 mV steps), Accuracy ±50 mV
  • Overdischarge release voltage n (n = 1, 2): 2.0 V to 3.4 V, Accuracy ±100 mV
• Two-level overcurrent detection (overcurrent 1, overcurrent 2)
  • Overcurrent detection voltage 1: 0.05 V, 0.08 V to 0.30 V (10 mV steps), Accuracy ±15 mV
  • Overcurrent detection voltage 2: 1.2 V (fixed), Accuracy ±300 mV
• Delay times (overcharge, overdischarge, overcurrent) are generated by an internal circuit (external capacitors are unnecessary).
• 0 V battery charge function available/unavailable are selectable.
• Charger detection function: The overdischarge hysteresis is released by detecting negative voltage at the VM pin (-0.7 V typ.) (Charger detection function).
• High-withstand voltage devices, Absolute maximum rating: 28 V
• Wide operating temperature range: -40°C to +85°C
• Low current consumption
  • Operation mode: 10 μA max. (+25°C)
  • Power-down mode: 0.1 μA max. (+25°C)
• Lead-free, Sn 100%, halogen-free

• Lithium-ion rechargeable battery packs
• Lithium polymer rechargeable battery packs
