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.

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. 13 BATTERY PROTECTION IC WITH CELL-BALANCE FUNCTION S-8209A Series Rev.3.8_00  Battery Protection IC Connection Examples Regarding the operation of protection circuit with the S-8209A series for series-connected batteries, refer to the application note "S-8209A Series Usage Guidelines". 1.
