Test Circuits
1. Overcharge detection voltage, overcharge hysteresis voltage
(Test circuit 1)
1. 1 Overcharge detection voltage n (VCUn
)
Set V1 = V2 = V3 = V4 = V5 = VCU − 0.05 V. The overcharge detection voltage 1 (VCU1) is the V1 voltage when the CO
pin’s output changes after the voltage of V1 has been gradually increased.
Overcharge detection voltage (VCUn) (n = 2 to 5) can be determined in the same way as when n = 1.
1. 2 Overcharge hysteresis voltage n (VHCn
)
Set V1 = VCU + 0.05 V, V2 = V3 = V4 = V5 = 2.5 V. The overcharge hysteresis voltage 1 (VHC1) is the difference
between V1 voltage and VCU1 when the CO pin's output changes after the V1 voltage has been gradually decreased.
Overcharge hysteresis voltage (VHCn) (n = 2 to 5) can be determined in the same way as when n = 1.

)
)

time.
2. 2 Output current of Nch open-drain output product
Set SW1 and SW2 to OFF.
2. 2. 1 Active "H"
(1) CO pin leakage current "L" (ICOLL
)
Set SW2 to ON after setting V1 = 5.5 V, V2 to V5 = 3.0 V, V7 = 17.5 V. I2 is the CO pin leakage current "L"
(ICOLL) at that time.
(2) CO pin sink current (ICOL
)
Set V1 to V5 = 3.5 V, V7 = 0.5 V. I2 is the CO pin sink current (ICOL) at that time.
2. 2. 2 Active "L"
(1) CO pin leakage current "L" (ICOLL
)
Set SW2 to ON after setting V1 to V5 = 3.5 V, V7 = 17.5 V. I2 is the CO pin leakage current "L" (ICOLL) at that
time.

2. 3 Output current of Pch open-drain output product
Set SW1 and SW2 to OFF.
2. 3. 1 Active "H"
(1) CO pin source current (ICOH
)
Set SW1 to ON after setting V1 = 5.5 V, V2 to V5 = 3.0 V, V6 = 0.5 V. I1 is the CO pin source current (ICOH) at
that time.
(2) CO pin leakage current "H" (ICOLH
)
Set V1 to V5 = 3.5 V, V6 = 17.5 V. I1 is the CO pin leakage current "H" (ICOLH) at that time.
2. 3. 2 Active "L"
(1) CO pin source current (ICOH
)
Set SW1 to ON after setting V1 to V5 = 3.5 V, V6 = 0.5 V. I1 is the CO pin source current (ICOH) at that time.
(2) CO pin leakage current "H" (ICOLH
)
Set V1 = 5.5 V, V2 to V5 = 3.0 V, V6 = 17.5 V. I1 is the CO pin leakage current "H" (ICOLH) at that time.
3. Overcharge detection delay time (tCU)
(Test circuit 1)
Increase V1 up to 5.0 V after setting V1 = V2 = V3 = V4 = V5 = 3.5 V. The overcharge detection delay time (tCU) is the
time period until the CO pin output changes.
4. Overcharge timer reset delay time (tTR)
(Test circuit 1)
Increase V1 up to 5.0 V (first rise), and decrease V1 down to 3.5 V within tCU after setting V1 = V2 = V3 = V4 = V5 =
3.5 V. After that, increase V1 up to 5.0 V again (second rise), and detect the time period till the CO pin output changes.
When the period from when V1 has fallen to the second rise is short, CO pin output changes after tCU has elapsed since
the first rise. If the period is gradually made longer, CO pin output changes after tCU has elapsed since the second rise.
The overcharge timer reset delay time (tTR) is the period from V1 fall till the second rise at that time.
5. Transition time to test mode (tTST
(Test circuit 2)
)
Increase V6 up to 5.0 V, and decrease V6 again to 0 V after setting V1 = V2 = V3 = V4 = V5 = 3.5 V, and V6 = 0 V.
When the period from when V6 was raised to when it has fallen is short, if an overcharge detection operation is
performed subsequently, the delay time is tCU. However, when the period from when V6 is raised to when it has fallen is
gradually made longer, the delay time during the subsequent overcharge detection operation is shorter than tCU. The
transition time to test mode (tTST) is the period from when V6 was raised to when it has fallen at that time.

Rev.2.6_00
S-8215A Series
Operation
Remark Refer to " Battery Protection IC Connection Examples".
1. Normal status
If the voltage of each of the batteries is lower than "the overcharge detection voltage n (VCUn) + the overcharge
hysteresis voltage n (VHCn)", the CO pin output changes to "L" (Active "H") or "H" (Active L"). This is called normal
status.
2. Overcharge status
When the voltage of one of the batteries exceeds VCUn during charging under normal status and the status is retained
for the overcharge detection delay time (tCU) or longer, the CO pin output changes. This is called overcharge status.
Connecting FET to the CO pin provides charge control and a second protection.
If the voltage of each of the batteries is lower than VCUn + VHCn and the status is retained for 2.0 ms typ. or longer, the
S-8215A Series returns to normal status.
3. Overcharge timer reset function
When an overcharge release noise that forces the voltage of one of the batteries temporarily below VCUn is input during
tCU from when VCUn is exceeded to when charging is stopped, tCU is continuously counted if the time the overcharge
release noise persists is shorter than the overcharge timer reset delay time (tTR). Under the same conditions, if the time
the overcharge release noise persists is tTR or longer, counting of tCU is reset once. After that, when VCUn has been
exceeded, counting tCU resumes.

S-8215A Series
Rev.2.6_00
4. Test mode
The overcharge detection delay time (tCU) can be shortened by entering the test mode.
The test mode can be set by retaining the VDD pin voltage 5.0 V or more higher than the VC1 pin voltage for the
transition time to test mode (tTST) or longer. The status is retained by the internal latch and the test mode is retained
even if the VDD pin voltage is decreased to the same voltage as that of the VC1 pin voltage.
After that, the latch for retaining the test mode is reset and the S-8215A Series exits from test mode under the
overcharge status.

Caution 1. When the VDD pin voltage is decreased to lower than the UVLO voltage of 2 V typ., the
S-8215A Series exits from test mode.
2. Set the test mode when no batteries are overcharged.
3. The overcharge timer reset delay time (tTR) is not shortened in the test mode.

Caution 1. The above constants are subject to change without prior notice.
2. It has not been confirmed whether the operation is normal or not in circuits other than the above
example of connection. In addition, the example of connection shown above and the constants
will not guarantee successful operation. Perform thorough evaluation using the actual
application to set the constants.
3. R1 to R5 should be the same constant. C1 to C5 and CVDD should be the same constant.
4. Set RVDD, C1 to C5, and CVDD so that the condition (RVDD) × (C1 to C5, CVDD) ≥ 5 × 10−6 is satisfied.
5. Set R1 to R5, C1 to C5, and CVDD so that the condition (R1 to R5) × (C1 to C5, CVDD) ≥ 1 × 10−4 is
satisfied.
6. Since the CO pin may become detection status transiently when the battery is being connected,
connect the positive terminal of BAT1 last in order to prevent the three terminal protection fuse
from cutoff.

Precautions
•
Do not connect batteries charged with VCUn + VHCn or higher. If the connected batteries include a battery charged with
VCUn + VHCn or higher, the S-8215A series may become overcharge status after all pins are connected.
•
In some application circuits, even if an overcharged battery is not included, the order of connecting batteries may be
restricted to prevent transient output of CO detection pulses when the batteries are connected. Perform thorough
evaluation with the actual application circuit.
•
•
•
•
Before the battery connection, short-circuit the battery side pins RVDD and R1, shown in the figure in " Battery
Protection IC Connection Examples".
The application conditions for the input voltage, output voltage, and load current should not exceed the package power
dissipation.
Do not apply to this IC an electrostatic discharge that exceeds the performance ratings of the built-in electrostatic
protection circuit.
ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement of patents
owned by a third party by products including this IC.
