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 in the range from the charge overcurrent detection voltage (VCIOV) to 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-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), 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), 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 voltage at VSS pin 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), 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). 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 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 the charge overcurrent detection voltage (VCIOV) by removing the charger. Seiko Instruments Inc. 19 BATTERY PROTECTION IC FOR 1-CELL PACK S-8211C Series 3. Overdischarge Status Rev.5.0_00 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 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 -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 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 14) 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-8211C 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. 20 Seiko Instruments Inc. Rev.5.0_00 5. Charge Overcurrent Status BATTERY PROTECTION IC FOR 1-CELL PACK S-8211C Series When a battery in the normal status is in the status where the voltage of the VM pin is lower than the charge overcurrent detection voltage because the charge current is higher than the specified value and the status lasts for the charge overcurrent detection delay time, the charge control FET is turned off and charging is stopped. This status is called the charge overcurrent status. This IC will be restored to the normal status from the charge overcurrent status when, the voltage at the VM pin 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 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 S8211C 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 charging 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 charging 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 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. Seiko Instruments Inc. 21 BATTERY PROTECTION IC FOR 1-CELL PACK S-8211C Series 8. Delay Circuit The detection delay times are determined by dividing a clock of approximately 3.5 kHz by the counter. Rev.5.0_00 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 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. 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 is still lower than the overdischarge detection voltage, S-8211C Series shifts to the power-down status. 22 Seiko Instruments Inc. Rev.5.0_00 Timing Chart BATTERY PROTECTION IC FOR 1-CELL PACK S-8211C Series (1) Overcharge Detection, Overdischarge Detection VCU VCL (VCU − VHC) Battery voltage VDU (VDL + VHD) VDL DO pin voltage VDD VSS VDD CO pin voltage VSS VEB− VDD VM pin voltage VDIOV VSS VCIOV VEB− Charger connection Load connection Overcharge detection delay time (tCU) Mode *1 Overdischarge detection delay time (tDL) (1) (3) (1) (1) (2) *1.
