Test Circuit
This chapter describes how to test the S-8204A Series. In case of selecting to use it for 4-series cell battery,
set SEL pin = VDD. For 3-series cell battery, set SEL pin = VSS and short between VC3 pin and VC4 pin.
1. Current consumption during operation and power-down
(Test circuit 1)
1. 1 Current consumption during operation (IOPE)
The current at the VSS pin when V1 = V2 = V3 = V4 = 3.5 V and VVMP = VDD is the current
consumption during operation (IOPE).
1. 2 Current consumption during power-down (IPDN)
The current at the VSS pin when V1 = V2 = V3 = V4 = 1.5 V and VVMP = VSS is the current
consumption during power-down (IPDN).
2. Overcharge detection voltage, overcharge release voltage, overdischarge detection voltage,
overdischarge release voltage, discharge overcurrent detection voltage 1, discharge overcurrent
detection voltage 2, load short-circuit detection voltage, charge overcurrent detection voltage,
CTLC pin input voltage "H", CTLC pin input voltage "L", CTLD pin input voltage "H", CTLD pin
input voltage "L", SEL pin input voltage "H", SEL pin input voltage "L"
(Test circuit 2)
Confirm both COP pin and DOP pin are in "L" (its voltage level is VDS 0.1 V or less) after setting VVMP
= VSEL = VDD, VVINI = VCTLC = VCTLD = VSS, CCT pin = Open, CDT pin = Open, CIT pin = Open, V1 = V2
= V3 = V4 = 3.5 V. (This status is referred to as initial status.)
2. 1 Overcharge detection voltage (VCU1), overcharge release voltage (VCL1)
The overcharge detection voltage (VCU1) is a voltage at V1; when the COP pin's voltage is set to "H"
(its voltage level is VDS 0.9 V or more) after increasing a voltage at V1 gradually from the initial
status. After that, decreasing a voltage at V1 gradually, a voltage at V1 when the COP pin's voltage is
set to "L"; is the overcharge release voltage (VCL1).
2. 2 Overdischarge detection voltage (VDL1), overdischarge release voltage (VDU1)
The overdischarge detection voltage (VDL1) is a voltage at V1; when the DOP pin's voltage is set to "H"
after decreasing a voltage at V1 gradually from the initial status. After that, increasing a voltage at V1
gradually, a voltage at V1 when the DOP pin's voltage is set to "L"; is the overdischarge release
voltage (VDU1).
By changing the voltage at Vn (n = 2 to 4), users can define the overcharge detection voltage (VCUn),
the overcharge release voltage (VCLn), the overdischarge detection voltage (VDLn), the overdischarge
release voltage (VDUn) as well when n = 1.
2. 3 Discharge overcurrent detection voltage 1 (VDIOV1)
The discharge overcurrent detection voltage 1 (VDIOV1) is the VINI pin's voltage; when the DOP pin's
voltage is set to "H" after increasing the VINI pin's voltage gradually from the initial status.
2. 4 Discharge overcurrent detection voltage 2 (VDIOV2)
The discharge overcurrent detection voltage 2 (VDIOV2) is a voltage at the VINI pin; when a flowing
current from the CIT pin reaches 500 A or more after increasing the VINI pin's voltage gradually from
the initial status.
2. 5 Load short-circuit detection voltage (VSHORT)
The load short-circuit detection voltage (VSHORT) is the VINI pin's voltage; when the DOP pin's voltage
is set to "H" after increasing the VINI pin's voltage gradually from the initial status after setting the CIT
pin's voltage to the VSS level.

2. 6 Charge overcurrent detection voltage (VCIOV)
The charge overcurrent detection voltage (VCIOV) is the VINI pin's voltage; when the COP pin's voltage
is set to "H" after decreasing the VINI pin's voltage gradually from the initial status.
2. 7 CTLC pin input voltage "H" (VCTLCH), CTLC pin input voltage "L" (VCTLCL)
The CTLC pin input voltage "H" (VCTLCH) is the CTLC pin's voltage; when the COP pin's voltage is set
to "H" after increasing the CTLC pin's voltage gradually from the initial status. After that, decreasing
the CTLC pin's voltage gradually, the CTLC pin's voltage when the COP pin's voltage is set to "L"; is
the CTLC pin input voltage "L" (VCTLCL).
2. 8 CTLD pin input voltage "H" (VCTLDH), CTLD pin input voltage "L" (VCTLDL)
The CTLD pin input voltage "H" (VCTLDH) is the CTLD pin's voltage; when the DOP pin's voltage is set
to "H" after increasing the CTLD pin's voltage gradually from the initial status. After that, decreasing
the CTLD pin's voltage gradually, the CTLD pin's voltage when the DOP pin's voltage is set to "L"; is

Operation
Remark Refer to " Connection Example of Battery Protection IC".
1. Normal status
In the S-8204A Series, both of COP pin and DOP pin get the VSS level; when the voltage of each of the
batteries is in the range of overdischarge detection voltage (VDLn) to overcharge detection voltage (VCUn),
and due to the discharge or charge current, the VINI pin's voltage is in the range of charge overcurrent
detection voltage (VCIOV) to discharge overcurrent detection voltage 1 (VDIOV1). This is the normal status.
At this time, the charge FET and the discharge FET are on.
2. Overcharge status
In the S-8204A Series, when the voltage of one of the batteries increases to the level of more than VCUn,
the COP pin is set in high impedance. This is the overcharge status. The COP pin is pulled up to EB by
an external resistor so that the charge FET is turned off and it stops charging.
This overcharge status is released if either condition mentioned below is satisfied;
(1) In case that the VMP pin voltage is set 39 / 40 VDS or more; the voltage of each of the batteries is
in the level of overcharge release voltage (VCLn) or less.
(2) In case that the VMP pin voltage is set 39 / 40 VDS or less; the voltage of each of the batteries is
in the level of VCUn or less.
3. Overdischarge status
In the S-8204A Series, when the voltage of one of the batteries decreases to the level of less than VDLn,
the DOP pin voltage gets the VDD level. This is the overdischarge status. At this time, the discharge FET
is turned off and it stops discharging.
This overdischarge status is released / maintained if either condition mentioned below is satisfied;
(1) To release; the VMP pin voltage is in the level of more than VDD, the voltage of each of the
batteries is in the VDLn level or more.
(2) To release; the VMP pin voltage is VDS / 2 or more and the VMP pin voltage is in the level of less
than VDD; the voltage of each of the batteries is in the level of overdischarge release voltage (VDUn)
or more.
(3) The VMP pin voltage is VDS / 2 or less, the S-8204A Series maintains the power-down function.
3. 1 Power-down function
In the S-8204A Series, when it reaches the overdischarge status, the VMP pin is pulled down to the
VSS level by a resistor between VMP pin and VSS pin (RVMS). If the VMP pin voltage decreases to the
level of VDS / 2 or less, the power-down function starts to operate and almost every circuit in the
S-8204A Series stops working.
The power-down function is released if the following condition is satisfied.
(1) The VMP pin voltage gets VDS / 2 or more.

4. Discharge overcurrent status
In the S-8204A Series, in batteries in the normal status, the discharging current increases more than a
certain value. As a result, if the status in which the VINI pin voltage increases to the level of VDIOV1 or
more, the DOP pin gets the VDD level. This is the discharge overcurrent status. At this time, the discharge
control FET is turned off and it stops discharging.
The S-8204A Series has three levels for discharge overcurrent detection (VDIOV1, VDIOV2, VSHORT). In the
status of discharge overcurrent, the COP pin is set in high impedance. The VMP pin is pulled up to the
VDD level by a resistor between VMP pin and VDD pin (RVMD).
The S-8204A Series' operations against discharge overcurrent detection voltage 2 (VDIOV2) and load short-
circuit detection voltage (VSHORT) are as well in VDIOV1.
The discharge overcurrent status is released if the following condition is satisfied.
(1) The VMP pin voltage gets VDS 1.2 V (typ.) or more.
5. Charge overcurrent status
In the S-8204A Series, in batteries in the normal status, the charge current increases more than a certain
value. As a result, if the status in which the VINI pin voltage decreases to the level of VCIOV or less, the
COP pin is set in high impedance. This is the charge overcurrent status. At this time, the charge control
FET is turned off and it stops charging.
In this charge overcurrent status, the VMP pin is pulled up to the VDD level by RVMD. Also in the
overdischarge status, the function of charge overcurrent detection works.
The charge overcurrent status is released if the following condition is satisfied.
(1) The VMP pin voltage gets VDS or less.
6. 0 V battery charge function
In the S-8204A Series, regarding how to charge a discharged battery (0 V battery), users are able to
select either function mentioned below.
(1) Allow to charge a 0 V battery (enable to charge a 0 V battery)
A 0 V battery is charged;
when the voltage of a charger is 0 V battery starting charger voltage (V0CHA) or more.
(2) Inhibit charging a 0 V battery (unable to charge a 0 V battery)
A 0 V battery is not charged;
when the voltage of a charger is 0 V battery charge inhibition battery voltage (V0INH) or less.
Caution When the VDD pin voltage is less than the minimum value of operation voltage between
VDD pin and VSS pin (VDSOP), the operation of the S-8204A Series is not assured.

7. Delay time setting
In the S-8204A Series, users are able to set delay time for the period; from detecting the voltage of one of
the batteries or detecting changes in the voltage at the VINI pin, to the output to the COP pin, DOP pin.
Each delay time is determined by a resistor in the S-8204A Series and an external capacitor.
In the overchage detection, when the voltage of one of the batteries gets VCUn or more, the S-8204 starts
charging to the CCT pin's capacitor (CCCT) via the CCT pin's internal resistor (RINC). After a certain period,
the COP pin is set in high impedance if the voltage at the CCT pin reaches the CCT pin detection voltage
(VCCT). This period is overcharge detection delay time (tCU).
tCU is calculated using the following equation (VDS = V1 V2 V3 V4).
tCU [s] = ln (1 VCCT / VDS ) CCCT [F] RINC [M]
= ln (1 0.7 (typ.)) CCCT [F] 8.31 [M] (typ.)
= 10.0 [M] (typ.) CCCT [F]
Overdischarge detection delay time (tDL), discharge overcurrent detection delay time 1 (tDIOV1), discharge
overcurrent detection delay time 2 (tDIOV2), charge overcurrent detection delay time (tCIOV) are calculated
using the following equations as well.
tDL [ms] = ln (1 VCDT / VDS) CCDT [F] RIND [k]
tDIOV1 [ms] = ln (1 VCIT / VDS) CCIT [F] RINI1 [k]
tDIOV2 [ms] = ln (1 VCIT / VDS) CCIT [F] RINI2 [k]
tCIOV [ms] = ln (1 VCIT / VDS) CCIT [F] RINI1 [k]
In case CCCT = CCDT = CCIT = 0.1 [F], each delay time tCU, tDL, tDIOV1, tDIOV2, tCIOV is calculated as follows.
tCU [s] = 10.0 [M] (typ.) 0.1 [F] = 1.0 [s] (typ.)
tDL [ms] = 1000 [k] (typ.) 0.1 [F] = 100 [ms] (typ.)
tDIOV1 [ms] = 200 [k] (typ.) 0.1 [F] = 20 [ms] (typ.)
tDIOV2 [ms] = 20 [k] (typ.) 0.1 [F] = 2.0 [ms] (typ.)
tCIOV [ms] = 200 [k] (typ.) 0.1 [F] = 20 [ms] (typ.)
Load short-circuit detection delay time (tSHORT) is fixed internally.

8. CTLC pin and CTLD pin
The S-8204A Series has two pins to control output voltage.
The CTLC pin controls the output voltage from the COP pin, the CTLD pin controls the output voltage
from the DOP pin. Thus it is possible for users to control the output voltages from the COP pin and DOP
pin independently. These controls precede the battery protection circuit.

9. SEL pin
The S-8204A Series has a pin to switch-control the protection for 3-cell or 4-cell battery.
The overdischarge detection for V4-cell is inhibited by setting the SEL pin "L", so that short-circuiting the
V4 cell does not allow the overdischarge detection. This setting makes it possible to use the S-8204A
Series for 3-cell protection. The SEL pin precedes the battery protection circuit. Be sure to use the SEL
pin in "H" or "L".

*1. Set up a filter constant to be RVSS CVSS = 47 F and to be RVC1 CVC1 = RVC2 CVC2 = RVC3 CVC3
= RVC4 CVC4 = RVSS CVSS.
Caution 1. The above constants may be changed without notice.
2. It is recommended that filter constants between VDD pin and VSS pin should be set
approximately to 47 F .
e.g., CVSS RVSS = 1.0 F 47 = 47 F
Sufficient evaluation of transient power supply fluctuation and overcurrent protection
function with the actual application is needed to determine the proper constants.
Contact our sales office in case the constants should be set to other than 47 F • .
3. It has not been confirmed whether the operation is normal in circuits other than the
above example of connection. In addition, the example of connection shown above and
the constants do not guarantee proper operation. Perform thorough evaluation using an
actual application to set the constant.

Precautions
The application conditions for the input voltage, output voltage, and load current should not exceed the
package power dissipation.
Batteries can be connected in any order; however, there may be cases when discharging cannot be
performed when a battery is connected. In such a case, short the VMP pin and VDD pin or connect the
battery charger to return the IC to the normal mode.
If both an overcharge battery and an overdischarge battery are included among the whole batteries, the
condition is set in overcharge status and overdischarge status. Therefore either charging or discharging is
impossible.
Do not apply an electrostatic discharge to this IC 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
by products including this IC of patents owned by a third party.
