Battery Protection IC with Cell-Balance Function S-8209A Series

The S-8209A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes a high-accuracy voltage detection circuit and a delay circuit. This IC has a transmission function and two types of cell-balance function so that users are also able to configure a protection circuit with series multi-cell.

*Application Note: S-8209A Series Usage Guidelines

7.0 µA max.
Lead-free product

*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step.)
*2. Overcharge detection voltage > Cell-balance detection voltage
(Overcharge detection voltage is always set higher than Cell-balance detection voltage)
*3. Cell-balance release voltage = Cell-balance detection voltage − Cell-balance hysteresis voltage
(Cell-balance hysteresis voltage is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step.)
*4. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage is selectable in 0 V, in 0.1 V to 0.7 V in 100 mV step.)

Applications

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