When the battery voltage is in the range from overdischarge detection voltage (VDL) to overcharge detection voltage (VCU), and the VM pin voltage is in the range from the charge overcurrent detection voltage (VCIOV) to discharge overcurrent detection voltage (VDIOV), the S-8211C Series 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 set the VM pin's voltage at the level of the charge overcurrent detection voltage (VCIOV) or more and the discharge overcurrent detection voltage (VDIOV) or less by connecting the charger. The S-8211C Series then returns to 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-8211C 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 the charge overcurrent detection voltage (VCIOV), and is lower than the discharge overcurrent detection voltage (VDIOV), the S-8211C 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), the S-8211C Series releases the overcharge status when the battery voltage falls below the overcharge detection voltage (VCU). The discharge is started by connecting a load after the overcharge detection, the VM pin voltage rises more than the VSS pin voltage due to the Vf voltage of the parasitic diode, 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), the S-8211C Series releases the overcharge status when the battery voltage is lower than or equal to the overcharge detection voltage (VCU). For the actual application boards, changing the battery voltage and the charger voltage simultaneously enables to measure the overcharge release voltage (VCL). In this case, the charger is always necessary to have the equivalent voltage level to the battery voltage. The charger keeps VM pin voltage higher than or equal to the charge overcurrent detection voltage (VCIOV) and lower than or equal to the discharge overcurrent detection voltage (VDIOV). The S-8211C Series releases the overcharge status when the battery voltage falls below the overcharge release voltage (VCL). Caution 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 m, 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 the charge overcurrent detection voltage (VCIOV) by removing the charger.

Overdischarge status 3. 1 With power-down 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-8211C 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 S-8211C Series (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 -0.7 V typ., the S-8211C 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 -0.7 V typ., the S-8211C Series releases the overdischarge status when the battery voltage reaches overdischarge release voltage (VDU) or higher. 3. 2 Without power-down 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-8211C 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 S-8211C Series (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 -0.7 V typ., the S-8211C 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 -0.7 V typ., the S-8211C 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 VM pin voltage is equal to or higher than the discharge overcurrent detection voltage (VDIOV) because the discharge current is higher than the specified value and the status lasts for the discharge overcurrent detection delay time (tDIOV), 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 S-8211C Series. However, the VM pin voltage is at the VDD potential due to the load as long as the load is connected. When the load is disconnected completely, the VM pin returns to the VSS potential. If the S-8211C Series detects that the VM pin voltage returns to discharge overcurrent detection voltage (VDIOV) or lower, the discharge overcurrent status is restored to the normal status. The S-8211C Series will be restored to the normal status from discharge overcurrent detection status even when the VM pin voltage 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 status. 20 Seiko Instruments Inc. BATTERY PROTECTION IC FOR 1-CELL PACK S-8211C Series Rev.7.5_00 5. Charge overcurrent status When a battery in the normal status is in the status where the VM pin voltage is lower than the charge overcurrent detection voltage (VCIOV) because the charge current is higher than the specified value and the status lasts for the charge overcurrent detection delay time (tCIOV), the charge control FET is turned off and charging is stopped. This status is called the charge overcurrent status. The S-8211C Series will be restored to the normal status from the charge overcurrent status when the VM pin voltage returns to charge overcurrent detection voltage (VCIOV) or higher by removing the charger. The charge overcurrent detection function does not work in the overdischarge 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 charge overcurrent status. 6. 0 V Battery charge 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 S-8211C Series enters the normal status. Caution 1. 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 charge function. 2. The 0 V battery charge function has higher priority than the charge overcurrent detection function. Consequently, a product in which use of the 0 V battery charge function is enabled charges a battery forcibly and the charge overcurrent cannot be detected when the battery voltage is lower than overdischarge detection voltage (VDL). 7. 0 V Battery charge 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 charge function. Seiko Instruments Inc. 21 BATTERY PROTECTION IC FOR 1-CELL PACK S-8211C Series Rev.7.5_00 8. Delay circuit The detection delay times are determined by dividing a clock of approximately 3.5 kHz by the counter. Remark 1. 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-8211C Series turns the discharging control FET off within the load short-circuiting detection delay time (tSHORT) from the time of detecting VSHORT. VDD DO Pin tD VSS Load short-circuiting detection delay time (tSHORT) 0 tD tSHORT Time VDD VSHORT VM Pin VDIOV VSS Time Figure 10 2. With power-down 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 S-8211C 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 (tDL) is still lower than the overdischarge detection voltage (VDL), the S-8211C Series shifts to the power-down status. Without power-down 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 S-8211C 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 (tDL) is still lower than the overdischarge detection voltage (VDL), the S-8211C Series shifts to the overdischarge status. 22 Seiko Instruments Inc.

If the withstand voltage between the gate and source is lower than the charger voltage, the FET may be destroyed. If a high resistor is connected to R1, 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 or higher as R1 for ESD protection. If a capacitor of less than 0.022 F is connected to C1, DO pin may oscillate when load short-circuiting is detected. Be sure to connect a capacitor of 0.022 F or higher to C1. If a resistor of 2 k or higher is connected to R2, the charge current may not be cut when a high-voltage charger is connected.
