Caution Unless otherwise specified, the output voltage levels “H” and “L” at CO pin (VCO) and DO pin (VDO) are judged by the threshold voltage (1.0 V) of the N-channel FET. Judge the CO pin level with respect to VVM and the DO pin level with respect to VSS. (1) Overcharge Detection Voltage, Overcharge Release Voltage (Test Condition 1, Test Circuit 1) Overcharge detection voltage (VCU) is defined as the voltage between the VDD pin and VSS pin at which VCO goes from “H” to “L” when the voltage V1 is gradually increased from the starting condition of V1 = 3.5 V. Overcharge release voltage (VCL) is defined as the voltage between the VDD pin and VSS pin at which VCO goes from “L” to “H” when the voltage V1 is then gradually decreased. Overcharge hysteresis voltage (VHC) is defined as the difference between overcharge detection voltage (VCU) and overcharge release voltage (VCL). (2) Overdischarge Detection Voltage, Overdischarge Release Voltage (Test Condition 2, Test Circuit 2) Overdischarge detection voltage (VDL) is defined as the voltage between the VDD pin and VSS pin at which VDO goes from “H” to “L” when the voltage V1 is gradually decreased from the starting condition of V1 = 3.5 V, V2 = 0 V. Overdischarge release voltage (VDU) is defined as the voltage between the VDD pin and VSS pin at which VDO goes from “L” to “H” when the voltage V1 is then gradually increased. Overdischarge hysteresis voltage (VHD) is defined as the difference between overdischarge release voltage (VDU) and overdischarge detection voltage (VDL). (3) Discharge Overcurrent Detection Voltage (Test Condition 3, Test Circuit 2) Discharge overcurrent detection voltage (VDIOV) is defined as the voltage between the VM pin and VSS pin whose delay time for changing VDO from “H” to “L” lies between the minimum and the maximum value of discharge overcurrent delay time when the voltage V2 is increased rapidly (within 10 µs) from the starting condition of V1 = 3.5 V, V2 = 0 V. (4) Load Short-circuiting Detection Voltage (Test Condition 3, Test Circuit 2) Load short-circuiting detection voltage (VSHORT) is defined as the voltage between the VM pin and VSS pin whose delay time for changing VDO from “H” to “L” lies between the minimum and the maximum value of load short-circuiting delay time when the voltage V2 is increased rapidly (within 10 µs) from the starting condition of V1 = 3.5 V, V2 = 0 V. (5) Operating Current Consumption (Test Condition 4, Test Circuit 2) The operating current consumption (IOPE) is the current that flows through the VDD pin (IDD) under the set conditions of V1 = 3.5 V and V2 = 0 V (normal status). (6) Charger detection voltage (= the detection voltage for irregular charging current) (Test Condition 4, Test Circuit 2) The charger detection voltage (VCHA) is the voltage between the VM and VSS pin; when gradually increasing V1 at V1 = 1.8 V, V2 = 0 V to set V1 = VDL+(VHD/2), after that, decreasing V2 gradually from 0 V so that VDO goes “L” to “H”. Measurement of the charger detection voltage is available for the product with overdischarge hysteresis VHD ≠ 0 only. The detection voltage for irregular charging current is the voltage between the VM and VSS pin; when gradually decreasing V2 at V1 = 3.5 V, V2 = 0 V and VCO goes “H” to “L”. The value of the detection voltage for irregular charging current is equal to the charger detection voltage (VCHA).

(11) CO Pin Resistance “L” (Test Condition 6, Test Circuit 4) The CO pin resistance “L” (RCOL) is the resistance at the CO pin under the set conditions of V1 = 4.5 V, V2 = 0 V, V3 = 0.5 V. (12) DO Pin Resistance “H” (Test Condition 7, Test Circuit 4) The DO pin H resistance (RDOH) is the resistance at the DO pin under the set conditions of V1 = 3.5 V, V2 = 0 V, V4 = 3.0 V. (13) DO Pin Resistance “L” (Test Condition 7, Test Circuit 4) The DO pin L resistance (RDOL) is the resistance at the DO pin under the set conditions of V1 = 1.8 V, V2 = 0 V, V4 = 0.5 V. (14) Overcharge Detection Delay Time (Test Condition 8, Test Circuit 5) The overcharge detection delay time (tCU) is the time needed for VCO to change from “H” to “L” just after the voltage V1 momentarily increases (within 10 µs) from overcharge detection voltage (VCU) −0.2 V to overcharge detection voltage (VCU) +0.2 V under the set conditions of V2 = 0 V. (15) Overdischarge Detection Delay Time (Test Condition 8, Test Circuit 5) The overdischarge detection delay time (tDL) is the time needed for VDO to change from “H” to “L” just after the voltage V1 momentarily decreases (within 10 µs) from overcharge detection voltage (VDL) +0.2 V to overcharge detection voltage (VDL) −0.2 V under the set condition of V2 = 0 V.

BATTERY PROTECTION IC FOR 1-CELL PACK S-8211D Series
Remark Refer to the “Battery Protection IC Connection Example”.
1. Normal Status
This IC monitors the voltage of the battery connected between the VDD pin and VSS pin and the voltage difference between the VM pin and VSS pin to control charging and discharging. When the battery voltage is in the range from overdischarge detection voltage (VDL) to overcharge detection voltage (VCU), and the VM pin voltage is not more than the discharge overcurrent detection voltage (VDIOV), the IC turns both the charging and discharging control FETs on. This condition is called the normal status, and in this condition charging and discharging can be carried out freely. The resistance (RVMD) between the VM pin and VDD pin, and the resistance (RVMS) between the VM pin and VSS pin are not connected in the normal status. Caution When the battery is connected for the first time, discharging may not be enabled. In this case, short the VM pin and VSS pin or connect the charger to restore the normal status.
2. Overcharge Status
When the battery voltage becomes higher than overcharge detection voltage (VCU) during charging in the normal status and detection continues for the overcharge detection delay time (tCU) or longer, the S-8211D Series turns the charging control FET off to stop charging. This condition is called the overcharge status. The resistance (RVMD) between the VM pin and VDD pin, and the resistance (RVMS) between the VM pin and VSS pin are not connected in the overcharge status. The overcharge status is released in the following two cases ( (1) and (2) ). (1) In the case that the VM pin voltage is higher than or equal to charger detection voltage (VCHA), and is lower than the discharge overcurrent detection voltage (VDIOV), S-8211D Series releases the overcharge status when the battery voltage falls below the overcharge release voltage (VCL). (2) In the case that the VM pin voltage is higher than or equal to the discharge overcurrent detection voltage (VDIOV), S-8211D Series releases the overcharge status when the battery voltage falls below the overcharge detection voltage (VCU). When the discharge is started by connecting a load after the overcharge detection, the VM pin voltage rises more than the voltage at VSS pin due to the Vf voltage of the parasitic diode. This is because the discharge current flows through the parasitic diode in the charging control FET. If this VM pin voltage is higher than or equal to the discharge overcurrent detection voltage (VDIOV), S-8211D Series releases the overcharge status when the battery voltage is lower than or equal to the overcharge detection voltage (VCU). Cautions 1. If the battery is charged to a voltage higher than overcharge detection voltage (VCU) and the battery voltage does not fall below overcharge detection voltage (VCU) even when a heavy load is connected, discharge overcurrent detection and load short-circuiting detection do not function until the battery voltage falls below overcharge detection voltage (VCU). Since an actual battery has an internal impedance of tens of mΩ, the battery voltage drops immediately after a heavy load that causes overcurrent is connected, and discharge overcurrent detection and load shortcircuiting detection function. 2. When a charger is connected after overcharge detection, the overcharge status is not released even if the battery voltage is below overcharge release voltage (VCL). The overcharge status is released when the VM pin voltage goes over charger detection voltage (VCHA) by removing the charger.

3. Overdischarge Status
Rev.4.5_00
With shutdown function When the battery voltage falls below overdischarge detection voltage (VDL) during discharging in the normal status and the detection continues for the overdischarge detection delay time (tDL) or longer, the S-8211D Series turns the discharging control FET off to stop discharging. This condition is called the overdischarge status. Under the overdischarge status, the VM pin voltage is pulled up by the resistor between the VM pin and VDD pin in the IC (RVMD). When voltage difference between the VM pin and VDD pin then is 1.3 V (Typ.) or lower, the current consumption is reduced to the power-down current consumption (IPDN). This condition is called the power-down status. The resistance (RVMS) between the VM pin and VSS pin is not connected in the power-down status and the overdischarge status. The power-down status is released when a charger is connected and the voltage difference between the VM pin and VDD pin becomes 1.3 V (typ.) or higher. When a battery in the overdischarge status is connected to a charger and provided that the VM pin voltage is lower than charger detection voltage (VCHA), the S-8211D Series releases the overdischarge status and turns the discharging FET on when the battery voltage reaches overdischarge detection voltage (VDL) or higher. When a battery in the overdischarge status is connected to a charger and provided that the VM pin voltage is not lower than charger detection voltage (VCHA), the S-8211D Series releases the overdischarge status when the battery voltage reaches overdischarge release voltage (VDU) or higher. Without shutdown function When the battery voltage falls below overdischarge detection voltage (VDL) during discharging in the normal status and the detection continues for the overdischarge detection delay time (tDL) or longer, the S-8211D Series turns the discharging control FET off to stop discharging. This condition is called the overdischarge status. Under the overdischarge status, the VM pin voltage is pulled up by the resistor between the VM pin and VDD pin in the IC (RVMD). The resistance (RVMS) between the VM pin and VSS pin is not connected in the overdischarge status. When a battery in the overdischarge status is connected to a charger and provided that the VM pin voltage is lower than charger detection voltage (VCHA), the S-8211D Series releases the overdischarge status and turns the discharging FET on when the battery voltage reaches overdischarge detection voltage (VDL) or higher. When a battery in the overdischarge status is connected to a charger and provided that the VM pin voltage is not lower than charger detection voltage (VCHA), the S-8211D Series releases the overdischarge status when the battery voltage reaches overdischarge release voltage (VDU) or higher.
4. Discharge Overcurrent Status (Discharge Overcurrent, Load Short-circuiting)
When a battery in the normal status is in the status where the voltage of the VM pin is equal to or higher than the discharge overcurrent detection voltage because the discharge current is higher than the specified value and the status lasts for the discharge overcurrent detection delay time, the discharge control FET is turned off and discharging is stopped. This status is called the discharge overcurrent status. In the discharge overcurrent status, the VM pin and VSS pin are shorted by the resistor between VM pin and VSS pin (RVMS) in the IC. However, the voltage of the VM pin is at the VDD potential due to the load as long as the load is connected. When the load is disconnected, the VM pin returns to the VSS potential. This IC detects the status when the impedance between the EB+ pin and EB− pin (Refer to the Figure 13) increases and is equal to the impedance that enables automatic restoration and the voltage at the VM pin returns to discharge overcurrent detection voltage (VDIOV) or lower, the discharge overcurrent status is restored to the normal status. Even if the connected impedance is smaller than automatic restoration level, the S-8211D Series will be restored to the normal status from discharge overcurrent detection status when the voltage at the VM pin becomes the discharge overcurrent detection voltage (VDIOV) or lower by connecting the charger. The resistance (RVMD) between the VM pin and VDD pin is not connected in the discharge overcurrent detection status.

5. Detection for irregular charging current
BATTERY PROTECTION IC FOR 1-CELL PACK S-8211D Series
During charging a battery which is in the normal status, if the VM pin voltage becomes lower than the charger detection voltage (VCHA) and this status is held longer than the overcharge detection delay time (tCU), S-8211D turns off the charge-control FET to stop charging. This is detection for irregular charging current. This function works in the case that the DO pin voltage is in “H”, and the VM pin voltage becomes lower than the charger detection voltage (VCHA). Thus if the irregular charger current flows in the battery in the overdischarge status, S-8211D turns off the charge-control FET to stop charging; the DO pin voltage goes in “H” so that the battery voltage becomes higher than the overdischarge detection voltage, and after the overcharge detection delay time (tcu). The status irregular charging current detection is released by the lower potential difference between the VM and VSS pin than the charger detection voltage (VCHA).
6. 0 V Battery Charging Function “Available”
This function is used to recharge a connected battery whose voltage is 0 V due to self-discharge. When the 0 V battery charge starting charger voltage (V0CHA) or a higher voltage is applied between the EB+ and EB− pins by connecting a charger, the charging control FET gate is fixed to the VDD pin voltage. When the voltage between the gate and source of the charging control FET becomes equal to or higher than the turnon voltage due to the charger voltage, the charging control FET is turned on to start charging. At this time, the discharging control FET is off and the charging current flows through the internal parasitic diode in the discharging control FET. When the battery voltage becomes equal to or higher than overdischarge release voltage (VDU), the S8211D Series enters the normal status. Caution Some battery providers do not recommend charging for a completely self-discharged battery. Please ask the battery provider to determine whether to enable or inhibit the 0 V battery charging function.
7. 0 V Battery Charging Function “Unavailable”
This function inhibits recharging when a battery that is internally short-circuited (0 V battery) is connected. When the battery voltage is the 0 V battery charge inhibition battery voltage (V0INH) or lower, the charging control FET gate is fixed to the EB− pin voltage to inhibit charging. When the battery voltage is the 0 V battery charge inhibition battery voltage (V0INH) or higher, charging can be performed. Caution Some battery providers do not recommend charging for a completely self-discharged battery. Please ask the battery provider to determine whether to enable or inhibit the 0 V battery charging function.

9. Delay Circuit
The detection delay times are determined by dividing a clock of approximately 3.5 kHz by the counter.
Rev.4.5_00
Remark1. The discharge overcurrent detection delay time (tDIOV) and the load short-circuiting detection delay time (tSHORT) start when the discharge overcurrent detection voltage (VDIOV) is detected. When the load shortcircuiting detection voltage (VSHORT) is detected over the load short-circuiting detection delay time (tSHORT) after the detection of discharge overcurrent detection voltage (VDIOV), the S-8211D turns the discharging control FET off within tSHORT from the time of detecting VSHORT.
VDD DO Pin tD VSS Load short-circuiting detection delay time (tSHORT) VDD VSHORT VM Pin VDIOV VSS Time 0 ≤ tD ≤ tSHORT Time
Figure 10 2. With shutdown function When any overcurrent is detected and the overcurrent continues for longer than the overdischarge detection delay time (tDL) without the load being released, the status changes to the power-down status at the point where the battery voltage falls below overdischarge detection voltage (VDL). When the battery voltage falls below overdischarge detection voltage (VDL) due to overcurrent, the S8211D Series turns the discharging control FET off via overcurrent detection. In this case, if the recovery of the battery voltage is so slow that the battery voltage after the overdischarge detection delay time is still lower than the overdischarge detection voltage, S-8211D Series shifts to the power-down status. Without shutdown function When any overcurrent is detected and the overcurrent continues for longer than the overdischarge detection delay time (tDL) without the load being released, the status changes to the overdischarge status at the point where the battery voltage falls below overdischarge detection voltage (VDL). When the battery voltage falls below overdischarge detection voltage (VDL) due to overcurrent, the S8211D Series turns the discharging control FET off via overcurrent detection. In this case, if the recovery of the battery voltage is so slow that the battery voltage after the overdischarge detection delay time is still lower than the overdischarge detection voltage, S-8211D Series shifts to the overdischarge status.

*1. If the threshold voltage of an FET is low, the FET may not cut the charging current. If an FET with a threshold voltage equal to or higher than the overdischarge detection voltage is used, discharging may be stopped before overdischarge is detected. *2. If the withstanding voltage between the gate and source is lower than the charger voltage, the FET may be destroyed. *3. If R1 has a high resistance, the voltage between VDD pin and VSS pin may exceed the absolute maximum rating when a charger is connected in reverse since the current flows from the charger to the IC. Insert a resistor of 100 Ω or higher as R1 for ESD protection. *4. If a capacitor of less than 0.022 µF is connected to C1, DO pin may oscillate when load short-circuiting is detected. Be sure to connect a capacitor of 0.022 µF or higher to C1. *5. If R2 has a resistance higher than 4 kΩ, the charging current may not be cut when a high-voltage charger is connected. Caution 1. The above constants may be changed without notice. 2. It has not been confirmed whether the operation is normal or not in circuits other than the above example of connection. In addition, the example of connection shown above and the constant do not guarantee proper operation. Perform through evaluation using the actual application to set the constant.
