Battery Protection IC for 1-Cell Pack (Secondary Protection) S-8216A Series

The S-8216A Series is used for secondary protection of lithium-ion / lithium polymer rechargeable batteries, and incorporates a high-accuracy voltage detection circuit and a delay circuit.
The S-8216A Series has functions with an overcharge detection and a discharge overcurrent detection.


High-accuracy voltage detection circuit
Overcharge detection voltage : 4.000 V to 5.000 V (5 mV step) Accuracy ±15 mV
Overcharge release voltage : 3.600 V to 4.950 V*1 Accuracy ±50 mV
Discharge overcurrent detection voltage : 0.003 V to 0.100 V (0.5 mV step) Accuracy ±1.5 mV
Detection delay time is generated only by an internal circuit (external capacitors are unnecessary).
Output logic is selectable
Active "H", active "L"
Output form
CMOS output
Wide operation temperature range
Ta = −40°C to +85°C
Low current consumption
During operation: 2.0 μA typ., 4.0 μA max. (Ta = +25°C)
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 0.05 V to 0.4 V in 50 mV step.)

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.
