Overcurrent Monitoring IC For Multi-serial-cell Pack S-8269B Series

The S-8269B Series is an overcurrent monitoring IC for multi-serial-cell pack including high-accuracy voltage detection circuits and delay circuits.
By using an external overcurrent detection resistor, the S-8269B Series realizes high-accuracy overcurrent protection with less effect from temperature change.

The S-8269A series with CTL pin is also available. For details, please contact our sales offices.


High-accuracy voltage detection circuit
Discharge overcurrent detection voltage 1: 0.0030 V to 0.1000 V (0.5 mV step) Accuracy ±1.5 mV
Discharge overcurrent detection voltage 2: 0.010 V to 0.100 V (1 mV step) Accuracy ±3 mV
Load short-circuiting detection voltage: 0.020 V to 0.100 V (1 mV step) Accuracy ±5 mV
Charge overcurrent detection voltage: −0.1000 V to −0.0030 V (0.5 mV step) Accuracy ±1.5 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary)

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
