Caution Unless otherwise specified, the VM pin voltage is based on VSS. 1. Normal status 1. 1 With charge overcurrent detection function The S-8252 Series 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 S-8252 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 voltage at the level of VCIOV or more and VDIOV or less by connecting the charger. The S-8252 Series then returns to the normal status. 1. 2 Without charge overcurrent detection function The S-8252 Series 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 charger detection voltage (VCHA) to discharge overcurrent detection voltage (VDIOV), The S-8252 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 voltage at the level of VCHA or more and VDIOV or less by connecting the charger. The S-8252 Series then returns to the normal status. 2. Overcharge status When the battery voltage becomes higher than VCU during charging in the normal status and detection continues for the overcharge detection delay time (tCU) or longer, the S-8252 Series turns the charging control FET off to stop charging. This condition is called the overcharge status. RVMD and RVMS 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 lower than VDIOV, the S-8252 Series releases the overcharge status when the battery voltage falls below VCL. (2) In the case that the VM pin voltage is higher than or equal to VDIOV, the S-8252 Series releases the overcharge status when the battery voltage falls below 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, 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 VDIOV, the S-8252 Series releases the overcharge status when the battery voltage is lower than or equal to VCU. Caution 1. If the battery is charged to a voltage higher than VCU and the battery voltage does not fall below VCU even when a heavy load is connected, discharge overcurrent detection and load shortcircuiting detection do not function until the battery voltage falls below 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 short-circuiting detection function. 2. If a charger is connected after the overcharge detection, the overcharge status is not released even when the battery voltage falls below VCL. The S-8252 Series releases the overcharge status when the VM pin voltage returns to VCIOV (or VCHA when without charge overcurrent detection function) or higher by removing the charger. 16 Rev.4.0_00 BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK S-8252 Series 3. Overdischarge status When the battery voltage falls below overdischarge detection voltage (VDL) during discharging in the normal status and the condition continues for the overdischarge detection delay time (tDL) or longer, the S-8252 Series turns the discharging control FET off to stop discharging. This condition is called the overdischarge status. Under the overdischarge status, the VM pin and VDD pin are shorted by RVMD in the S-8252 Series. The VM pin is pulled up by RVMD. RVMS is not connected in the overdischarge status. 3. 1 With power-down function Under the overdischarge status, when voltage difference between the VM pin and VDD pin is 0.8 V typ. or lower, the power-down function works and the current consumption is reduced to the current consumption during power-down (IPDN). By connecting a battery charger, the power-down function is released when the VM pin voltage is 0.7 V typ. or lower. • When a battery is not connected to a charger and the VM pin voltage ≥ 0.7 V typ., the S-8252 Series maintains the overdischarge status even when the battery voltage reaches VDU or higher. • When a battery is connected to a charger and 0.7 V typ. > the VM pin voltage > −0.7 V typ., the battery voltage reaches VDU or higher and the S-8252 Series releases the overdischarge status. • When a battery is connected to a charger and −0.7 V typ. ≥ the VM pin voltage, the battery voltage reaches VDL or higher and the S-8252 Series releases the overdischarge status. 3. 2 Without power-down function The power-down function does not work even when voltage difference between the VM pin and VDD pin is 0.8 V typ. or lower. • When a battery is not connected to a charger and the VM pin voltage ≥ 0.7 V typ., the battery voltage reaches VDU or higher and the S-8252 Series releases the overdischarge status. • When a battery is connected to a charger and 0.7 V typ. > the VM pin voltage > −0.7 V typ., the battery voltage reaches VDU or higher and the S-8252 Series releases the overdischarge status. • When a battery is connected to a charger and −0.7 V typ. ≥ the VM pin voltage, the battery voltage reaches VDL or higher and the S-8252 Series releases the overdischarge status. 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 VDIOV because the discharge current is equal to or higher than the specified value and the status lasts for the discharge overcurrent detection delay time (tDIOV) or longer, 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 RVMS in the S-8252 Series. 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. If the voltage at the VM pin returns to VDIOV or lower, the S-8252 Series releases the discharge overcurrent status. RVMD is not connected in the discharge overcurrent detection status. 5. Charge overcurrent status (with charge overcurrent detection function) When a battery in the normal status is in the status where the voltage of the VM pin is equal to or lower than VCIOV because the charge current is equal to or higher than the specified value and the status lasts for the charge overcurrent detection delay time (tCIOV) or longer, the charge control FET is turned off and charging is stopped. This status is called the charge overcurrent status. The S-8252 Series releases the charge overcurrent status when the voltage at the VM pin returns to VCIOV or higher by removing the charger. The charge overcurrent detection function does not work in the overdischarge status. RVMD and RVMS are not connected in the charge overcurrent detection status. 6. Abnormal charge current status (without charge overcurrent detection function) If the VM pin voltage falls below the charger detection voltage (VCHA) during charging under normal status and it continues for the overcharge detection delay time (tCU) or longer, the charging control FET turns off and charging stops. This action is called the abnormal charge current status. Abnormal charge current status is released when the voltage difference between VM pin and VSS pin becomes less than charger detection voltage (VCHA). 17 BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK S-8252 Series Rev.4.0_00 7. 0 V battery charge enabled 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 potential. When the voltage between the gate and source of the charging control FET becomes equal to or higher than the threshold 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 VDU, the S-8252 Series returns to the normal status. Caution 1. Some battery providers do not recommend recharging for a completely self-discharged battery. Please ask the battery provider to determine whether to enable or inhibit the 0 V battery charge. 2. The 0 V battery charge has higher priority than the charge overcurrent detection function. Consequently, a product in which use of the 0 V battery charge is enabled charges a battery forcibly and the charge overcurrent cannot be detected when the battery voltage is lower than VDL. 8. 0 V battery charge inhibited This function inhibits charging 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 V0INH or higher, charging can be performed. Caution Some battery providers do not recommend recharging for a completely self-discharged battery. Please ask the battery provider to determine whether to enable or inhibit the 0 V battery charge. 9. Delay circuit The detection delay times are determined by dividing a clock of approximately 4 kHz by the counter. Remark tDIOV and tSHORT start when VDIOV is detected. When VSHORT is detected over tSHORT after VDIOV, the S-8252 Series turns the discharging control FET off within tSHORT from the time of detecting VSHORT.

If the threshold voltage of an FET is low, the FET may not cut the charge 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. If the withstand voltage between the gate and source is equal to or lower than the charger voltage, the FET may be destroyed. An accuracy of overcharge detection voltage is guaranteed by R1 = 470 Ω. Connecting resistors with other values worsen the accuracy. In case of connecting larger resistor to R1, the voltage between the VDD pin and VSS pin may exceed the absolute maximum rating because the current flows to the S-8252 Series from the charger due to reverse connection of charger. Connect a resistor of 150 Ω or more to R1 for ESD protection. When connecting a resistor of 150 Ω or less to R1 or R2 or a capacitor of 0.068 μF or less to C1 or C2, the S-8252 Series may malfunction when power dissipation is largely fluctuated.
