*1. The delay time is set by the external capacitor.
But the discharge overcurrent release delay time (tDIOVR) and charge overcurrent release delay time (tCIOVR) are
calculated by discharge overcurrent detection delay time (tDIOV) and charge overcurrent detection delay time (tCIOV) as
the following equations. 1 [ms] (typ.) is the internal delay time of the S-8205A Series.
(1) tDIOVR = tDIOV 10 1 [ms] (typ.), tCIOVR = tCIOV 10 1 [ms] (typ.)
(2) tDIOVR = tDIOV 0.05 1 [ms] (typ.), tCIOVR = tCIOV 0.05 1 [ms] (typ.)
Moreover, refer to "7. Delay Time Setting" in " Operation" for calculational methods of delay times.

BATTERY PROTECTION IC FOR 4-SERIES OR 5-SERIES CELL PACK
S-8205A/B Series
Rev.1.9_01
Operation
Remark Refer to " Connection Examples of Battery Protection IC".
1. Normal Status
In the S-8205A/B Series, both of CO pin and DO pin get the VDD 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
current, the VINI pin's voltage is in the range of charge overcurrent detection voltage (VCIOV) to discharge overcurrent
detection voltage (VDIOV). This is the normal status. At this time, the charge and discharge FETs are on.
2. Overcharge Status
In the S-8205A/B Series, the voltage of one of the batteries increases to the level of more than VCUn, the CO pin is set
in high impedance. This is the overcharge status. The CO pin is pulled down to EB by an external resistor so that
the charge FET is turned off and it stops charging.
The overcharge status is released if either condition mentioned below is satisfied;
(1) In case that the CO pin voltage is 1 / 50 VDS or less, and the voltage of each of the batteries which are VCUn
or more is in the level of overcharge release voltage (VCLn) or less.
(2) In case that the CO pin voltage is 1 / 50 VDS or more, and the voltage of each of the batteries is in the level
of VCUn or less.
3. Overdischarge Status
In the S-8205A/B Series, when the voltage of one of the batteries decreases to the level of VDLn or less, the DO pin
voltage gets the VSS level. This is the overdischarge status. The discharge FET is turned off and it stops discharging.
The overdischarge status is released if either condition mentioned below is satisfied;
(1) In case that the VM pin voltage is in the level of less than VSS, and the voltage of each of the batteries is in the
level of VDLn or more.
(2) In case that the VM pin voltage is VDS / 5 (typ.) or less and the VM pin voltage is in the level of more than VSS
,
and the voltage of each of the batteries which are VDLn or less is in the level of overdischarge release voltage
(VDUn) or more.
3. 1 With power-down function
In the S-8205A/B Series, when it reaches the overdischarge status, the VM pin is pulled up to the VDD level by a
resistor between VM pin and VDD pin (RVMD). If the VM pin voltage and the CO pin voltage increase to the level of
VDS / 5 (typ.) or more, respectively, the power-down function starts to operate and almost every circuit in the
S-8205A/B Series stops working.
The power-down function is released if either condition mentioned below is satisfied;
(1) The VM pin voltage gets VDS / 5 (typ.) or less.
(2) The CO pin voltage gets VDS / 5 (typ.) or less.
4. Discharge Overcurrent Status
The discharging current increases to a certain value or more. As a result, if the status in which the VINI pin voltage
increases to the level of VDIOV or more, the DO pin gets the VSS level. This is the discharge overcurrent status. The
discharge control FET is turned off and it stops discharging. In the status of discharge overcurrent, the CO pin is set
in high impedance. The VM pin is pulled down to the VSS level by a resistor between VM pin and VSS pin (RVMS).
S-8205A/B Series has two levels for discharge overcurrent detection (VDIOV, VSHORT).
The S-8205A/B Series' actions against load short circuit detection voltage (VSHORT) are as well in VDIOV
.
The discharge overcurrent status is released if the following condition is satisfied.
(1) The VM pin voltage gets VDS / 10 (typ.) or less.

5. Charge Overcurrent Status
In the S-8205A/B Series, the charge current increases to a certain value or more. As a result, if the status in which
the VINI pin voltage decreases to the level of VCIOV or less, the CO pin is set in high impedance. This is the charge
overcurrent status. The charge control FET is turned off and it stops charging. In this charge overcurrent status, DO
pin gets the VSS level. The VM pin is pulled up to the VDD level by resistance between VM pin and VDD pin (RVMD).
The charge overcurrent status is released if the following condition is satisfied.
(1) The CO pin voltage gets 1 / 50 VDS (typ.) or more.
6. 0 V Battery Charge Function
In the S-8205A/B Series, regarding how to charge a discharged battery (0 V battery), users are able to select either
function mentioned below.
(1) Enable to charge a 0 V battery
A 0 V battery is charged when charger voltage is more than 0 V battery charge starting charger voltage
(V0CHA).
(2) Inhibit charging a 0 V battery
A 0 V battery is not charged when the voltage of one of the batteries 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 S-8205A/B Series' action is not assured.
7. Delay Time Setting
In the S-8205A/B 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 CO pin, DO pin. Each delay time is
determined by a resistor in the IC and an external capacitor.
In the overchage detection, when the voltage of one of the batteries gets VCUn or more, the S-8205A/B Series starts
charging to the CCT pin's capacitor (CCCT) via the CCT pin's internal resistor (RCCT). After a certain period, the CO 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 V5).
t
CU [s] = ln ( 1 VCCT / VDS ) CCCT [F] RCCT [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 (tDIOV), charge overcurrent
detection delay time (tCIOV) are calculated using the following equations as well.
t
t
t
DL [ms] = ln ( 1 VCDT / VDS) CCDT [F] RCDT [k]
DIOV [ms] = ln ( 1 VCIT / VDS) CCIT [F] RCIT [k]
CIOV [ms] = ln ( 1 VCIT / VDS) CCIT [F] RCIT [k]
In case CCCT = CCDT = CCIT = 0.1 [F], each delay time tCU, tDL, tDIOV, tCIOV is calculated as follows.
CU [s] = 10.0 [M] (typ.) 0.1 [F] = 1.0 [s] (typ.)
t
tDL [ms] = 1000 [k] (typ.) 0.1 [F] = 100 [ms] (typ.)
tDIOV [ms] = 200 [k] (typ.) 0.1 [F] = 20 [ms] (typ.)
tCIOV [ms] = 200 [k] (typ.) 0.1 [F] = 20 [ms] (typ.)
Discharge overcurrent release delay time (tDIOVR) and charge overcurrent release delay time (tCIOVR) can be selected
from two types, and they are calculated by tDIOV and tCIOV as the following equations. 1 [ms] (typ.) is the internal delay
time of the S-8205A/B Series.
(1) tDIOVR = tDIOV 10 1 [ms] (typ.), tCIOVR = tCIOV 10 1 [ms] (typ.)
(2) tDIOVR = tDIOV 0.05 1 [ms] (typ.), tCIOVR = tCIOV 0.05 1 [ms] (typ.)
Load short circuit detection delay time (tSHORT) is fixed internally.

8. CTLC Pin and CTLD Pin
The S-8205A/B Series has two pins to control.
The CTLC pin controls the CO pin, the CTLD pin controls the DO pin. Thus it is possible for users to control the CO
pin and DO pin independently. These controls precede the battery protection circuit.

C
.
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 100 F.
e.g., CVDD RVDD = 1.0 F 100 = 100 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 100 F.
3. It has not been confirmed whether the operation is normal or not in circuits other than the example
of connection. In addition, the example of connection and the constant do not guarantee proper
operation. Perform thorough evaluation using the 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 this case, short the VM pin and VSS pin or connect the battery charger to return 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.
