ABLIC S-8253CAI-T8T1U

The S-8253C/D Series is a protection ICs for 2-series or 3-series cell lithium-ion rechargeable battery and includes high-accuracy voltage detector and delay circuit. This IC is suitable for protecting lithium-ion battery packs from overcharge, overdischarge and overcurrent.

• High-accuracy voltage detection for each cell
  • Overcharge detection voltage n (n = 1 to 3): 3.900 V to 4.400 V (50 mV step), Accuracy ±25 mV
  • Overcharge release voltage n (n = 1 to 3): 3.800 V to 4.400 V, Accuracy ±50 mV
  • Overdischarge detection voltage n (n = 1 to 3): 2.000 V to 3.000 V (100 mV step), Accuracy ±80 mV
  • Overdischarge release voltage n (n = 1 to 3): 2.000 V to 3.400 V, Accuracy ±100 mV
• Three-level overcurrent detection (Including load short circuiting detection)
  • Overcurrent detection voltage 1: 0.050 V to 0.300 V (50 mV step), Accuracy ±25 mV
  • Overcurrent detection voltage 2: 0.500 V (Fixed)
