Refer to " Battery Protection IC Connection Example". 2. Unless otherwise specified, the VM pin voltage is based on VSS. 1. Normal status The S-8240A Series monitors the voltage of the battery connected between VDD pin and VSS pin, the voltage between 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 charge overcurrent detection voltage (VCIOV) to discharge overcurrent detection voltage (VDIOV), the S-8240A Series turns both the charge and discharge control FETs on. This condition is called the normal status, and in this condition charging and discharging can be carried out freely. The resistance between VDD pin and VM pin (RVMD), and the resistance between VM pin and VSS pin (RVMS) are not connected in the normal status. Caution When the battery is connected for the first time, the S-8240A Series may not be in the normal status. In this case, short VM pin and VSS pin, or set the VM pin voltage at the level of VCIOV or more and at the level of VDIOV or less by connecting the charger. The S-8240A Series then becomes the normal status. 2. Overcharge status 2. 1 VCL ≠ VCU (Product in which overcharge release voltage differs from overcharge detection voltage) When the battery voltage becomes higher than VCU during charging in the normal status and the condition continues for the overcharge detection delay time (tCU) or longer, the S-8240A Series turns the charge control FET off to stop charging. This condition is called the overcharge status. The overcharge status is released in the following two cases. (1) In the case that the VM pin voltage is lower than VDIOV, the S-8240A Series releases the overcharge status when the battery voltage falls below overcharge release voltage (VCL). (2) In the case that the VM pin voltage is equal to or higher than VDIOV, the S-8240A 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 by the Vf voltage of the parasitic diode than the VSS pin voltage, because the discharge current flows through the parasitic diode in the charge control FET. If this VM pin voltage is equal to or higher than VDIOV, the S-8240A Series releases the overcharge status when the battery voltage is equal to or lower than VCU. Caution 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 short-circuiting 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. 2 VCL = VCU (Product in which overcharge release voltage is the same as overcharge detection voltage) When the battery voltage becomes higher than VCU during charging in the normal status and the condition continues for the overcharge detection delay time (tCU) or longer, the S-8240A Series turns the charge control FET off to stop charging. This condition is called the overcharge status. In the case that the VM pin voltage is equal to or higher than 0 V typ., the S-8240A Series releases the overcharge status when the battery voltage falls below 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 short-circuiting 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. When a charger is connected after overcharge detection, the overcharge status is not released even if the battery voltage is below VCL. The overcharge status is released when the VM pin voltage goes over 0 V typ. by removing the charger. 17 BATTERY PROTECTION IC FOR 1-CELL PACK S-8240A Series Rev.1.4_00 3. Overdischarge status When the battery voltage falls below VDL during discharging in the normal status and the condition continues for the overdischarge detection delay time (tDL) or longer, the S-8240A Series turns the discharge control FET off to stop discharging. This condition is called the overdischarge status. Under the overdischarge status, VDD pin and VM pin are shorted by RVMD in the S-8240A Series. The VM pin voltage 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 VDD pin and VM 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-8240A 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 V typ., the battery voltage reaches VDU or higher and the S-8240A Series releases the overdischarge status. • When a battery is connected to a charger and 0 V typ. ≥ the VM pin voltage, the battery voltage reaches VDL or higher and the S-8240A Series releases the overdischarge status. 3. 2 Without power-down function The power-down function does not work even when voltage difference between VDD pin and VM 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-8240A Series releases the overdischarge status. • When a battery is connected to a charger and 0.7 V typ. > the VM pin voltage > 0 V typ., the battery voltage reaches VDU or higher and the S-8240A Series releases the overdischarge status. • When a battery is connected to a charger and 0 V typ. ≥ the VM pin voltage, the battery voltage reaches VDL or higher and the S-8240A 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 VM pin voltage 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. 4. 1 Release condition of discharge overcurrent status "load disconnection" and release voltage of discharge overcurrent status "VDIOV" Under the discharge overcurrent status, VM pin and VSS pin are shorted by RVMS in the S-8240A Series. However, the VM pin voltage is the VDD pin voltage due to the load as long as the load is connected. When the load is disconnected, VM pin returns to the VSS pin voltage. When the VM pin voltage returns to VDIOV or lower, the S-8240A Series releases the discharge overcurrent status. RVMD is not connected in the discharge overcurrent status. 4. 2 Release condition of discharge overcurrent status "load disconnection" and release voltage of discharge overcurrent status "VRIOV" Under the discharge overcurrent status, VM pin and VSS pin are shorted by RVMS in the S-8240A Series. However, the VM pin voltage is the VDD pin voltage due to the load as long as the load is connected. When the load is disconnected, VM pin returns to the VSS pin voltage. When the VM pin voltage returns to VRIOV or lower, the S-8240A Series releases the discharge overcurrent status. RVMD is not connected in the discharge overcurrent status. 4. 3 Release condition of discharge overcurrent status "charger connection" Under the discharge overcurrent status, VM pin and VDD pin are shorted by RVMD in the S-8240A Series. When a battery is connected to a charger and the VM pin voltage returns to VDIOV or lower, the S-8240A Series releases the discharge overcurrent status. RVMS is not connected in the discharge overcurrent status. 18 Rev.1.4_00 BATTERY PROTECTION IC FOR 1-CELL PACK S-8240A Series 5. Charge overcurrent status When a battery in the normal status is in the status where the VM pin voltage 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-8240A Series releases the charge overcurrent status when the VM pin voltage returns to 0 V typ. or higher by removing the charger. The charge overcurrent detection does not function in the overdischarge status. 6. 0 V battery charge function "available" This function is used to recharge a 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 charge control FET gate is fixed to the VDD pin voltage. When the voltage between the gate and source of the charge control FET becomes equal to or higher than the threshold voltage due to the charger voltage, the charge control FET is turned on to start charging. At this time, the discharge 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 VDL, the S-8240A Series enters the normal status. Caution 1. Some battery providers do not recommend charging for a completely self-discharged lithium-ion rechargeable 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 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 charge 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 charging for a completely self-discharged lithium-ion rechargeable battery. Please ask the battery provider to determine whether to enable or inhibit the 0 V battery charge function. 19 BATTERY PROTECTION IC FOR 1-CELL PACK S-8240A Series Rev.1.4_00 8. 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.
