tD s = ln (1VCDET / VDS) CCDT F RCDT M = ln (10.7(典型值) CCDT F 8.31 M (典型值) = 10.0 M(典型值) CCDT F CDT端子电容CCDT = 0.01 F时，输出端子延迟时间tD可使用上述公式计算求出。 tD s = 10.0 M(典型值) 0.01 F = 0.1 s (典型值) 在IC外部将CTLC、CTLD端子下拉到VSS电位的状态下接通电源后，请在指定的测定电路中测定RCDT以及CDT端子检测电压(VCDET)。 *2、在IC外部将CTLC、CTLD端子下拉到VSS电位使用时，流入VDD端子的电流(IDD)可按照如下公式计算求出。 IDD = IOPEICTLCHICTLDH测定电路工作原理说明1. 通常状态 S-8209A系列的VDDVSS间电压(VDS)比过放电检测电压(VDL)高，且低于过充电检测电压(VCU)，当CTLC输入端子电压(VCTLC) 低于CTLC端子高电压(VCTLCH)、CTLD输入端子电压(VCTLD)低于CTLD端子高电压(VCTLDH)的情况下，CO端子和DO端子均变为VSS电位。这称为通常状态。 2. 过充电状态 在VDSVCU或VCTLCVCTLCH的情况下，S-8209A系列的CO端子变为高阻抗。这称为过充电状态。 在VDS过充电解除电压(VCL)，且VCTLCCTLC端子低电压(VCTLCL)的情况下，S-8209A系列会解除过充电状态而恢复为通常状态。 3. 过放电状态 在VDSVDL或VCTLDVCTLDH的情况下，S-8209A系列的DO端子变为高阻抗。这称为过放电状态。在VDS过放电解除电压(VDU)，且VCTLDCTLD端子低电压(VCTLDL)的情况下，S-8209A系列会解除过放电状态而恢复为通常状态。 4. 电量平衡功能 在VDS电量平衡检测电压(VBU)的情况下，S-8209A系列将CB端子的电压设为VDD电位。这称为充电电量平衡功能。在VDSVBL（电量平衡解除电压）的情况下，S-8209A系列将CB端子的电压设为VSS电位。 接着，在VDSVDL、且VCTLDVCTLDH的情况下，S-8209A系列将CB端子的电压设为VDD电位。这称为放电电量平衡功能。在再次VCTLDVCTLDL或VDSVDL的情况下，S-8209A系列将CB端子的电压设为VSS电位。 5. 关于延迟电路 S-8209A系列可设置从检测到VDS的变化和VCTLC、VCTLD的变化后到CO端子、DO端子、CB端子的输出发生变化为止的延迟时间。延迟时间由IC内部的CDT端子电阻(RCDT)和CDT端子的外接电容(CCDT)而决定。 例如，进行过充电状态的检测时，在VDS超过VCU或VCTLCVCTLCH的情况下，可通过RCDT开始向CCDT充电。当CDTVSS间电压(VCDT)达到CDT端子检测电压(VCDET)时，S-8209A系列的CO端子变为高阻抗。输出端子的延迟时间tD可按照如下公式计算求出。 tDs = 10.0 M (典型值) CCDT F 延迟时间结束后，CCDT的电荷开始放电。 并且，DO端子、CB端子的各输出端子也可设定为相同长短的延迟时间。使用S-8209A系列的串联电池保护电路示例注意1、上述参数有可能不经预告而作更改。 2、上述连接示例以及参数并不作为保证电路工作的依据。请在实际的应用电路上进行充分的实测后再设定参数。注意事项*请注意输入输出电压、负载电流的使用条件，使IC内的功耗不超过封装的容许功耗。

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 pins resistance in the IC (RCDT) and the value of capacitor set externally at the CDT pin (CCDT). tD s = -ln (1-VCDET/VDS) CCDT F RCDT M = -ln (1-0.7 (Typ.) ) CCDT F 8.31 M (Typ.) = 10.0 M (Typ.) CCDT F In case of the capacitance of CDT pin CCDT = 0.01 F, the output pin delay time tD is calculated by using the above formula and as follows. tD s = 10.0 M (Typ.) 0.01 F = 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, CTLD pins to the level of VSS pin outside the IC. *2. In case of using CTLC, CTLD pins 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 + ICTLDHTest CircuitsOperation1. Normal Status In the S-8209A Series, both of CO and DO pin get the VSS level; the voltage between VDD and VSS (VDS) 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 Seri
