Rev.3.8_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
• Low current consumption
Ta = −40°C to +85°C
7.0 μA max.
• Lead-free, Sn 100%, halogen-free*7
*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

3. Please contact our sales representatives for products other than the above.
Users are able to select the overcharge detection voltage, overcharge release voltage, cell-balance detection
voltage and cell-balance release voltage from the range shown in Figure 2 and Figure 3.
Users are able to select how to combine the overcharge detection voltage (VCU) and the overcharge release
voltage (VCL) from the range A or B shown in Figure 2*1.
Similarly, select how to combine the cell-balance detection voltage (VBU) and the cell-balance release voltage
(VBL) from the range of C or D in Figure 3*2.
In selecting the combination of VCU and VCL from the range A, select the combination of VBU and VBL from the
range C. Similarly, in selecting the combination of VCU and VCL from the B range, select the combination of VBU
and VBL from the range D*3.

*1. In the S-8209A Series, users are able to set delay time for the output pins. By using the following formula, delay time is
calculated with the value of CDT pin’s resistance in the IC (RCDT) and the value of capacitor set externally at the CDT pin
(CCDT).
tD [s] = −ln (1 − VCDET / VDS) × CCDT [μF] × RCDT [MΩ]
= −ln (1 − 0.7 typ.) × CCDT [μF] × 8.31 MΩ typ.
= 10.0 MΩ typ. × CCDT [μF]
In case of the capacitance of CDT pin CCDT = 0.01 μF, the output pin delay time tD is calculated by using the above
formula and as follows.
tD [s] = 10.0 MΩ typ. × 0.01 μF = 0.1 s typ.
Test RCDT and the CDT pin detection voltage (VCDET) by test circuits shown in this datasheet after applying the power
supply while pulling-down the CTLC pin and the CTLD pin to the level of VSS pin outside the IC.
*2. In case of using CTLC pin and CTLD pin pulled-down to the level of VSS pin externally, the current flows into the VDD
pin (IDD) is calculated by the following formula.
IDD = IOPE + ICTLCH + ICTLDH

BATTERY PROTECTION IC WITH CELL-BALANCE FUNCTION
S-8209A Series
Rev.3.8_00
1. Normal status
In the S-8209A Series, both of CO pin and DO pin get the VSS level; the voltage (VDS) between VDD pin and VSS pin
is more than the overdischarge detection voltage (VDL), and is less than the overcharge detection voltage (VCU) and
respectively, the CTLC pin input voltage (VCTLC) < the CTLC pin voltage "H" (VCTLCH), the CTLD pin input voltage
(VCTLD) < the CTLD pin voltage "H" (VCTLDH). This is the normal status.
2. Overcharge status
In the S-8209A Series, the CO pin is in high impedance; when VDS gets VCU or more, or VCTLC gets VCTLCH or more.
This is the overcharge status.
If VDS gets the overcharge release voltage (VCL) or less, and VCTLC gets the CTLC pin voltage "L" (VCTLCL) or less, the
S-8209A Series releases the overcharge status to return to the normal status.
3. Overdischarge status
In the S-8209A Series, the DO pin is in high impedance; when VDS gets VDL or less, or VCTLD gets VCTLDH or more.
This is the overdischarge status.
If VDS gets the overdischarge release voltage (VDU) or more, and VCTLD gets the CTLD pin voltage "L" (VCTLDL) or less,
the S-8209A Series releases the overdischarge status to return to the normal status.
4. Cell-balance function
In the S-8209A Series, the CB pin gets the level of VDD pin; when VDS gets the cell-balance detection voltage (VBU
)
or more. This is the charge cell-balance function.
If VDS gets the cell-balance release voltage (VBL) or less again, the S-8209A Series sets the CB pin the level of VSS
pin.
In addition, the CB pin gets the level of VDD pin; when VDS is more than VDL, and VCTLD is VCTLDH or more. This is the
discharge cell-balance function.
If VCTLD gets VCTLDL or less, or VDS is VDL or less again, the S-8209A Series sets the CB pin the level of VSS
.
5. Delay circuit
In the S-8209A Series, users are able to set delay time which is from detection of changes in VDS, VCTLC, VCTLD to
output to the CO pin, DO pin and CB pin.
For example in the detection of overcharge status, when VDS exceeds VCU, or VCTLC gets VCTLCH or more, charging to
CCDT starts via RCDT. If the voltage (VCDT) between CDT pin and VSS pin reaches the CDT pin detection voltage
(VCDET), the CO pin is in high impedance. The output pin delay time tD is calculated by the following formula.
tD [s] = 10.0 MΩ typ. × CCDT [μF]
The electric charge in CCDT starts to be discharged when the delay time has finished.
The delay time that users have set for the CO pin, as seen above, is settable for each output pin DO, CB.
