BATTERY PROTECTION IC
WITH CELL-BALANCE FUNCTION
Rev.3.5_00
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.
The S-8209A Series 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.
Features

• Settable delay time by external capacitor for output pin
• Control charging, discharging, cell-balance by CTLC pin and CTLD pin
• Two types of cell-balance function; charge / discharge*6
• Wide range of operation temperature
Ta = −40°C to +85°C
• Low current consumption
• Lead-free, Sn 100%, halogen-free*7
7.0 μA max.

*1. Regarding selection of overcharge detection voltage, overcharge release voltage, cell-balance detection voltage
and cell-balance release voltage, refer to Remark 3 in "3. Product name list" of " Product Name Structure"
*2. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage is selectable in 0 V to 0.4 V, in 50 mV step.)
*3. Select as to overcharge detection voltage > cell-balance detection voltage.
*4. Cell-balance release voltage = Cell-balance detection voltage − Cell-balance hysteresis voltage
(Cell-balance hysteresis voltage is selectable in 0 V to 0.4 V, in 50 mV step.)
*5. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage is selectable in 0 V to 0.7 V, in 100 mV step.)
*6. Also available the product without discharge cell-balance function
*7. Refer to " Product Name Structure" for details.
Applications
• Lithium-ion rechargeable battery pack
• Lithium polymer rechargeable battery pack
Packages
