S-82x5B Series Battery Monitoring ICs

ABLIC ICs are used for secondary protection of lithium-ion rechargeable batteries

Image of ABLIC S-82x5B Series Battery Monitoring ICsABLIC S-82x5B ICs are used for secondary protection of lithium-ion rechargeable batteries, incorporating high-accuracy voltage detection circuits and delay circuits in a small 8-pin package. Short-circuiting between cells makes it possible for serial connection of 3-cell to 5-cell. By cascade connection of these ICs, it is possible to protect 6-serial or more cells lithium-ion rechargeable battery packs.

Features
  • High-accuracy voltage detection circuit for each cell
    • Overcharge detection voltage n
      • 3,500 V to 4,700 V (5 mV steps)
      • Accuracy: ±15 mV to ±20 mV (TA = +25°C)
      • Accuracy: ±20 mV to ±25 mV (TA = -10°C to +60°C)
    • Overcharge release voltage n*1
      • 3.100 V to 4.700 V
      • Accuracy: ±50 mV
  • Delay times for overcharge detection are generated only by an internal circuit (external capacitors are unnecessary)
    • Overcharge detection delay time: 0.5 s, 1 s, 2 s, 4 s, 6 s, 8 s
  • CO pin output voltage is limited to 7.5 V max.
  • Overcharge timer reset function: available, unavailable
  • High withstand voltage: absolute maximum rating 28 V
  • Wide operating voltage range: 3.6 V to 24 V
  • Wide operating temperature range: TA = -40°C to +85°C
  • Low current consumption
  • During operation (3.4 V for each cell): 5.0 μA max.
  • Lead-free (Sn 100%), halogen-free
