BATTERY PROTECTION IC FOR 1-CELL PACK
Rev.1.0_00
The S-82A1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy
voltage detection circuits and delay circuits. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery
packs from overcharge, overdischarge, and overcurrent.
By using an external overcurrent detection resistor, the S-82A1A Series realizes high-accuracy overcurrent protection with less
effect from temperature change.

 Operation
Remark Refer to " Battery Protection IC Connection Example".
1. Normal status
The S-82A1A Series monitors the voltage of the battery connected between VDD pin and VSS pin, the voltage between
VINI 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 VINI pin voltage is in the range from charge
overcurrent detection voltage (VCIOV) to discharge overcurrent detection voltage 1 (VDIOV1), the S-82A1A 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, discharge may not be carried. In this case, short VM
pin and VSS pin, or set the VM pin voltage at the level of VCIOV or higher and at the level of VDIOV1 or
lower by connecting the charger. The S-82A1A 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-82A1A 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 0.35 V typ., the S-82A1A 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 0.35 V typ., the S-82A1A 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 0.35 V typ., the S-82A1A 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-82A1A 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 0.35 V typ. and the battery voltage falls below VCU, the
S-82A1A Series releases the overcharge status.
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 0.35 V typ., the S-82A1A Series
releases the overcharge status when the battery voltage is equal to or lower than 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 discharge
current flows and the VM pin voltage goes over 0.35 V typ. by removing the charger.
15
BATTERY PROTECTION IC FOR 1-CELL PACK
S-82A1A Series
Rev.1.0_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-82A1A 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-82A1A Series. The VM pin voltage is
pulled up by RVMD.
When connecting a charger in the normal status, the battery voltage reaches VDL or higher and the S-82A1A Series
releases the overdischarge status if the VM pin voltage falls below 0 V typ.
The battery voltage reaches the overdischarge release voltage (VDU) or higher and the S-82A1A Series releases the
overdischarge status if the VM pin voltage does not fall below 0 V typ.
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-82A1A 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-82A1A 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-82A1A 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-82A1A 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-82A1A 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-82A1A Series releases the overdischarge status.
4. Discharge overcurrent status (discharge overcurrent 1, discharge overcurrent 2, load short
circuiting)
When a battery in the normal status is in the status where the VINI pin voltage is equal to or higher than VDIOV1 because
the discharge current is equal to or higher than the specified value and the status lasts for the discharge overcurrent
detection delay time 1 (tDIOV1) 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 "VDIOV1"
Under the discharge overcurrent status, VM pin and VSS pin are shorted by RVMS in the S-82A1A 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, the VM pin returns to the VSS pin voltage. When the VM pin voltage returns to VDIOV1 or lower, the
S-82A1A 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-82A1A 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, the VM pin returns to the VSS pin voltage. When the VM pin voltage returns to VRIOV or lower, the
S-82A1A Series releases the discharge overcurrent status.
RVMD is not connected in the discharge overcurrent status.
16

BATTERY PROTECTION IC FOR 1-CELL PACK
S-82A1A Series
4. 3 Release condition of discharge overcurrent status "charger connection"
Under the discharge overcurrent status, VDD pin and VM pin are shorted by RVMD in the S-82A1A Series.
When a battery is connected to a charger and the VM pin voltage returns to VDIOV1 or lower, the S-82A1A Series
releases the discharge overcurrent status.
RVMS is not connected in the discharge overcurrent status.
5. Charge overcurrent status
When a battery in the normal status is in the status where the VINI 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-82A1A Series releases the charge overcurrent status when the discharge current flows and the VM pin voltage is
0.35 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 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 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-82A1A 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.
