1
The S-8241 Series is a series of lithium ion/lithium polymer rechargeable battery protection ICs incorporating high-accuracy
voltage detection circuits and delay circuits.
These ICs are suitable for protection of 1-cell lithium ion/lithium polymer rechargeable battery packs from overcharge,
overdischarge and overcurrent.
Features
(1) Internal high-accuracy voltage detection circuit
Overcharge detection voltage: 3.9 V to 4.4 V (5 mV-step)
Accuracy of ±25 mV (+25C) and ± 30 mV (5 to +55C)
Overcharge release voltage: 3.8 V to 4.4 V*1 Accuracy of ±50 mV
Overdischarge detection voltage: 2.0 V to 3.0 V (100 mV-step) Accuracy of ±80 mV
Overdischarge release voltage: 2.0 V to 3.4 V*2 Accuracy of ±100 mV
Overcurrent 1 detection voltage: 0.05 V to 0.32 V (5 mV-step) Accuracy of ±20 mV
Overcurrent 2 detection voltage: 0.5 V (fixed) Accuracy of ±100 mV
(2) A high voltage withstand device is used for charger connection pins
(VM and CO pins: Absolute maximum rating = 26 V)
(3) Delay times (overcharge: tCU; overdischarge: tDL; overcurrent 1: tlOV1; overcurrent 2: tlOV2) are generated
by an internal circuit. (External capacitors are unnecessary.) Accuracy of ±30%
(4) Internal three-step overcurrent detection circuit (overcurrent 1, overcurrent 2, and load short-circuiting)
(5) Either the 0 V battery charging function or 0 V battery charge inhibiting function can be selected.
(6) Products with and without a power-down function can be selected.
(7) Charger detection function and abnormal charge current detection function
The overdischarge hysteresis is released by detecting a negative VM pin voltage (typ. 1.3 V) (Charger detection
function).
If the output voltage at DO pin is high and the VM pin voltage becomes equal to or lower than the charger detection
voltage (typ. 1.3 V), the output voltage at CO pin goes low (Abnormal charge current detection function).
(8) Low current consumption
Operation: 3.0 A typ. 5.0 A max.
Power-down mode: 0.1 A max.
(9) Wide operation temperature range: 40C to +85C
(10) Lead-free, Sn 100%, halogen-free*3
*1. Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis
The overcharge hysteresis can be selected in the range 0.0 V, or 0.1 V to 0.4 V in 50 mV steps. (However, selection
“Overcharge release voltage<3.8 V” is enabled.)
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis
The overdischarge hysteresis can be selected in the range 0.0 V to 0.7 V in 100 mV steps. (However, selection
“Overdischarge release voltage3.4 V” is enabled.)
*3. Refer to “ Product Name Structure” for details.

Test Circuits
Caution Unless otherwise specified, the output voltage levels “H” and “L” at CO pin (VCO) and DO pin (VDO) are
judged by the threshold voltage (1.0 V) of the N-channel FET. Judge the CO pin level with respect to VVM
and the DO pin level with respect to VSS.
(1) Test Condition 1, Test Circuit 1
(Overcharge detection voltage, Overcharge release voltage, Overdischarge detection voltage, Overdischarge
release voltage)
The overcharge detection voltage (VCU) is defined by the voltage between VDD and VSS at which VCO goes “L” from “H”
when the voltage V1 is gradually increased from the normal condition V1 = 3.5 V and V2 = 0 V. The overcharge release
voltage (VCL) is defined by the voltage between VDD and VSS at which VCO goes “H” from “L” when the voltage V1 is
then gradually decreased.
Gradually decreasing the voltage V1, the overdischarge detection voltage (VDL) is defined by the voltage between VDD
and VSS at which VDO goes “L” from “H”. The overdischarge release voltage (VDU) is defined by the voltage between
VDD and VSS at which VDO goes “H” from “L” when the voltage V1 is then gradually increased.
(2) Test Condition 2, Test Circuit 1
(Overcurrent 1 detection voltage, Overcurrent 2 detection voltage, Load short-circuiting detection voltage)
The overcurrent 1 detection voltage (VIOV1) is defined by the voltage between VDD and VSS at which VDO goes “L” from
“H” when the voltage V2 is gradually increased from the normal condition V1 = 3.5 V and V2 = 0 V.
The overcurrent 2 detection voltage (VIOV2) is defined by the voltage between VDD and VSS at which VDO goes “L” from
“H” when the voltage V2 is increased at the speed between 1 ms and 4 ms from the normal condition V1 = 3.5 V and V2
= 0 V.
The load short-circuiting detection voltage (VSHORT) is defined by the voltage between VDD and VSS at which VDO goes
“L” from “H” when the voltage V2 is increased at the speed between 1 s and 50 s from the normal condition V1 = 3.5
V and V2 = 0 V.
(3) Test Condition 3, Test Circuit 1
(Charger detection voltage, ( = abnormal charge current detection voltage) )
Applied only for products with overdischarge hysteresis
Set V1 = 1.8 V and V2 = 0 V under overdischarge condition. Increase V1 gradually, set V1 = (VDU+VDL) / 2 (within
overdischarge hysteresis, overdischarge condition), then decrease V2 from 0 V gradually. The voltage between VM
and VSS at which VDO goes “H” from “L” is the charger detection voltage (VCHA).
Applied only for products without overdischarge hysteresis
Set V1 = 3.5 V and V2 = 0 V under normal condition. Decrease V2 from 0 V gradually. The voltage between VM and
VSS at which VCO goes “L” from “H” is the abnormal charge current detection voltage. The abnormal charge current
detection voltage has the same value as the charger detection voltage (VCHA).
(4) Test Condition 4, Test Circuit 1
(Normal operation current consumption, Power-down current consumption, Overdischarge current
consumption)
Set V1 = 3.5 V and V2 = 0 V under normal condition. The current IDD flowing through VDD pin is the normal operation
consumption current (IOPE).
For products with power-down function
Set V1 = V2 = 1.5 V under overdischarge condition. The current IDD flowing through VDD pin is the power-down
current consumption (IPDN).
For products without power-down function
Set V1 = V2 = 1.5 V under overdischarge condition. The current IDD flowing through VDD pin is the overdischarge
current consumption (IOPED).

(5) Test Condition 5, Test Circuit 1
(Internal resistance between VM and VDD, Internal resistance between VM and VSS)
Set V1 = 1.8 V and V2 = 0 V under overdischarge condition. Measure current IVM flowing through VM pin. 1.8V / |IVM|
gives the internal resistance (RVMD) between VM and VDD.
Set V1 = V2 = 3.5 V under overcurrent condition. Measure current IVM flowing through VM pin. 3.5 V / |IVM| gives the
internal resistance (RVMS) between VM and VSS.
(6) Test Condition 6, Test Circuit 1
(CO pin H resistance, CO pin L resistance)
Set V1 = 3.5 V, V2 = 0 V and V3 = 3.0 V under normal condition. Measure current ICO flowing through CO pin. 0.5 V /
|ICO| is the CO pin H resistance (RCOH).
Set V1 = 4.5 V, V2 = 0 V and V3 = 0.5 V under overcharge condition. Measure current ICO flowing through CO pin. 0.5
V / |ICO| is the CO pin L resistance (RCOL).
(7) Test Condition 7, Test Circuit 1
(DO pin H resistance, DO pin L resistance)
Set V1 = 3.5 V, V2 = 0 V and V4 = 3.0 V under normal condition. Measure current IDO flowing through DO pin. 0.5 V /
|IDO| gives the DO pin H resistance (RDOH).
Set V1 = 1.8 V, V2 = 0 V and V4 = 0.5 V under overdischarge condition. Measure current IDO flowing through DO pin.
0.5 V / |IDO| gives the DO pin L resistance (RDOL).
(8) Test Condition 8, Test Circuit 1
(Overcharge detection delay time, Overdischarge detection delay time)
Set V1 = 3.5 V and V2 = 0 V under normal condition. Increase V1 gradually to overcharge detection voltage VCU - 0.2 V
and increase V1 to the overcharge detection voltage VCU + 0.2 V momentarily (within 10 s). The time after V1 becomes
the overcharge detection voltage until VCO goes "L" is the overcharge detection delay time (tCU).
Set V1 = 3.5 V and V2 = 0 V under normal condition. Decrease V1 gradually to overdischarge detection voltage VDL +
0.2 V and decrease V1 to the overdischarge detection voltage VDL - 0.2 V momentarily (within 10 s). The time after V1
becomes the overdischarge detection voltage VDL until VDO goes "L" is the overdischarge detection delay time (tDL).
(9) Test Condition 9, Test Circuit 1
(Overcurrent 1 detection delay time, Overcurrent 2 detection delay time, Load short-circuiting detection delay
time, Abnormal charge current detection delay time)
Set V1 = 3.5 V and V2 = 0 V under normal condition. Increase V2 from 0 V to 0.35 V momentarily (within 10 s). The
time after V2 becomes overcurrent 1 detection voltage (VIOV1) until VDO goes "L" is overcurrent 1 detection delay time
(tIOV1).
Set V1 = 3.5 V and V2 = 0 V under normal condition. Increase V2 from 0 V to 0.7 V momentarily (within 1 s). The time
after V2 becomes overcurrent 1 detection voltage (VIOV1) until VDO goes "L" is overcurrent 2 detection delay time (tIOV2).
Caution The overcurrent 2 detection delay time starts when the overcurrent 1 is detected, since the delay
circuit is common.
Set V1 = 3.5 V and V2 = 0 V under normal condition. Increase V2 from 0 V to 3.0 V momentarily (within 1 s). The time
after V2 becomes the load short-circuiting detection voltage (VSHORT) until VDO goes "L" is the load short-circuiting
detection delay time (tSHORT).
Set V1 = 3.5 V and V2 = 0 V under normal condition. Decrease V2 from 0 V to -2.5 V momentarily (within 10 s). The
time after V2 becomes the charger detection voltage (VCHA) until VCO goes "L" is the abnormal charge current detection
delay time. The abnormal charge current detection delay time has the same value as the overcharge detection delay
time.

Operation
Remark Refer to the “ Battery Protection IC Connection Example”.
1. Normal Status
The S-8241 monitors the voltage of the battery connected to VDD and VSS pins and the voltage difference between VM
and VSS pins to control charging and discharging. When the battery voltage is in the range from the overdischarge
detection voltage (VDL) to the overcharge detection voltage (VCU), and the VM pin voltage is in the range from the
charger detection voltage (VCHA) to the overcurrent 1 detection voltage (VIOV1) (the current flowing through the battery is
equal to or lower than a specified value), the IC turns both the charging and discharging control FETs on. This status is
called normal status and in this status charging and discharging can be carried out freely.
2. Overcurrent Status
When the discharging current becomes equal to or higher than a specified value (the VM pin voltage is equal to or higher
than the overcurrent detection voltage) during discharging under normal status and the state continues for the
overcurrent detection delay time or longer, the S-8241 turns the discharging control FET off to stop discharging. This
status is called overcurrent status. (The overcurrent includes overcurrent 1, overcurrent 2, or load short-circuiting.)
The VM and VSS pins are shorted internally by the RVMS resistor under the overcurrent status. When a load is
connected, the VM pin voltage equals the VDD voltage due to the load.
The overcurrent status returns to the normal status when the load is released and the impedance between the EB+ and
EB- pins (see the Figure 12 for a connection example) becomes higher than the automatic recoverable impedance (see
the equation [1] below). When the load is removed, the VM pin goes back to the VSS potential since the VM pin is
shorted the VSS pin with the RVMS resistor. Detecting that the VM pin potential is lower than the overcurrent 1 detection
voltage (VIOV1), the IC returns to the normal status.
Automatic recoverable impedance = {Battery voltage / (Minimum value of overcurrent 1 detection voltage) 1} x (RVMS
maximum value) --- [1]
Example: Battery voltage = 3.5 V and overcurrent 1 detection voltage (VIOV1) = 0.1 V
Automatic recoverable impedance = (3.5 V / 0.07 V 1) x 200 k = 9.8 M
Remark The automatic recoverable impedance varies with the battery voltage and overcurrent 1 detection voltage
settings. Determine the minimum value of the open load using the above equation [1] to have automatic
recovery from the overcurrent status work after checking the overcurrent 1 detection voltage setting for the IC.

3. Overcharge Status
When the battery voltage becomes higher than the overcharge detection voltage (VCU) during charging under normal
status and the state continues for the overcharge detection delay time (tCU) or longer, the S-8241 turns the charging
control FET off to stop charging. This status is called the overcharge status.
The overcharge status is released in the following two cases ((1) and (2)) depending on the products with and without
overcharge hysteresis:
Products with overcharge hysteresis (overcharge detection voltage (V
CU
) > overcharge release voltage (V
CL
))
(1) When the battery voltage drops below the overcharge release voltage (VCL), the S-8241 turns the charging control
FET on and returns to the normal status.
(2) When a load is connected and discharging starts, the S-8241 turns the charging control FET on and returns to the
normal status. The release mechanism is as follows: the discharging current flows through an internal parasitic
diode of the charging FET immediately after a load is connected and discharging starts, and the VM pin voltage
increases about 0.7 V (Vf voltage of the diode) from the VSS pin voltage momentarily. The IC detects this voltage
(being higher than the overcurrent 1 detection voltage) and releases the overcharge status. Consequently, in the
case that the battery voltage is equal to or lower than the overcharge detection voltage (VCU), the IC returns to the
normal status immediately, but in the case the battery voltage is higher than the overcharge detection voltage (VCU),
the IC does not return to the normal status until the battery voltage drops below the overcharge detection voltage
(VCU) even if the load is connected. In addition if the VM pin voltage is equal to or lower than the overcurrent 1
detection voltage when a load is connected and discharging starts, the IC does not return to the normal status.
Remark If the battery is charged to a voltage higher than the overcharge detection voltage (VCU) and the battery
voltage does not drop below the overcharge detection voltage (VCU) even when a heavy load, which
causes an overcurrent, is connected, the overcurrent 1 and overcurrent 2 do not work until the battery
voltage drops below the overcharge detection voltage (VCU). Since an actual battery has, however, an
internal impedance of several dozens of m, and the battery voltage drops immediately after a heavy load
which causes an overcurrent is connected, the overcurrent 1 and overcurrent 2 work. Detection of load
short-circuiting works regardless of the battery voltage.
Products without overcharge hysteresis (Overcharge detection voltage (V
CU
) = Overcharge release voltage (V
CL
))
(1) When the battery voltage drops below the overcharge release voltage (VCL), the S-8241 turn the charging control
FET on and returns to the normal status.
(2) When a load is connected and discharging starts, the S-8241 turns the charging control FET on and returns to the
normal status. The release mechanism is explained as follows : the discharging current flows through an internal
parasitic diode of the charging FET immediately after a load is connected and discharging starts, and the VM pin
voltage increases about 0.7 V (Vf voltage of the diode) from the VSS pin voltage momentarily. Detecting this voltage
(being higher than the overcurrent 1 detection voltage), the IC increases the overcharge detection voltage about 50
mV, and releases the overcharge status. Consequently, when the battery voltage is equal to or lower than the
overcharge detection voltage (VCU) + 50 mV, the S-8241 immediately returns to the normal status. But the battery
voltage is higher than the overcharge detection voltage (VCU) + 50 mV, the S-8241 does not return to the normal
status until the battery voltage drops below the overcharge detection voltage (VCU) + 50 mV even if a load is
connected. If the VM pin voltage is equal to or lower than the overcurrent 1 detection voltage when a load is
connected and discharging starts, the S-8241 does not return to the normal status.
Remark If the battery is charged to a voltage higher than the overcharge detection voltage (VCU) and the battery
voltage does not drop below the overcharge detection voltage (VCU) + 50 mV even when a heavy load,
which causes an overcurrent, is connected, the overcurrent 1 and overcurrent 2 do not work until the
battery voltage drops bellow the overcharge detection voltage (VCU) + 50 mV. Since an actual battery has,
however, an internal impedance of several dozens of m, and the battery voltage drops immediately after
a heavy load which causes an overcurrent is connected, the overcurrent 1 and overcurrent 2 work.
Detection of load short-circuiting works regardless of the battery voltage.

4. Overdischarge Status
With power-down function
When the battery voltage drops below the overdischarge detection voltage (VDL) during discharging under normal status
and it continues for the overdischarge detection delay time (tDL) or longer, the S-8241 turns the discharging control FET
off and stops discharging. This status is called overdischarge status. After the discharging control FET is turned off, the
VM pin is pulled up by the RVMD resistor between VM and VDD in the IC. Meanwhile the potential difference between VM
and VDD drops below 1.3 V (typ.) (the load short-circuiting detection voltage), current consumption of the IC is reduced
to the power-down current consumption (IPDN). This status is called power-down status. The VM and VDD pins are
shorted by the RVMD resistor in the IC under the overdischarge and power-down statuses.
The power-down status is released when a charger is connected and the potential difference between VM and VDD
becomes 1.3 V (typ.) or higher (load short-circuiting detection voltage). At this time, the FET is still off. When the battery
voltage becomes the overdischarge detection voltage (VDL) or higher*1, the S-8241 turns the FET on and changes to the
normal status from the overdischarge status.
*1. If the VM pin voltage is no less than the charger detection voltage (VCHA), when the battery under overdischarge
status is connected to a charger, the overdischarge status is released (the discharging control FET is turned on) as
usual, provided that the battery voltage reaches the overdischarge release voltage (VDU) or higher.
Without power-down function
When the battery voltage drops below the overdischarge detection voltage (VDL) during discharging under normal status
and it continues for the overdischarge detection delay time (tDL) or longer, the S-8241 turns the discharging control FET
off and stops discharging. When the discharging control FET is turned off, the VM pin is pulled up by the RVMD resistor
between VM and VDD in the IC. Meanwhile the potential difference between VM and VDD drops below 1.3 V (typ.) (the
load short-circuiting detection voltage), current consumption of the IC is reduced to the overdischarge current
consumption (IOPED). This status is called overdischarge status. The VM and VDD pins are shorted by the RVMD resistor
in the IC under the overdischarge status.
When a charger is connected, the overdischarge status is released in the same way as explained above in respect to
products having the power-down function. For products without the power-down function, in addition, even if the charger
is not connected, the S-8241 turns the discharging control FET on and changes to the normal status from the
overdischarge status provided that the load is disconnected and that the potential difference between VM and VSS
drops below the overcurrent 1 detection voltage (VIOV1), since the VM pin is pulled down by the RVMS resistor between
VM and VSS in the IC when the battery voltage reaches the overdischarge release voltage (VDU) or higher.
5. Charger Detection
If the VM pin voltage is lower than the charger detection voltage (VCHA) when a battery in overdischarge status is
connected to a charger, overdischarge hysteresis is released, and when the battery voltage becomes equal to or higher
than the overdischarge detection voltage (VDL), the overdischarge status is released (the discharging control FET is
turned on). This action is called charger detection. (The charger detection reduces the time for charging in which
charging current flows through the internal parasitic diode in the discharging control FET) .
If the VM pin voltage is not lower than the charger detection voltage (VCHA) when a battery in overdischarge status is
connected to a charger, the overdischarge status is released (the discharging control FET is turned on) as usual, when
the battery voltage reaches the overdischarge release voltage (VDU) or higher.

6. Abnormal Charge Current Detection
If the VM pin voltage drops below the charger detection voltage (VCHA) during charging under the normal status and it
continues for the overcharge detection delay time (tCU) or longer, the S-8241 turns the charging control FET off and
stops charging. This action is called abnormal charge current detection.
Abnormal charge current detection works when the discharging control FET is on (DO pin voltage is “H”) and the VM pin
voltage drops below the charger detection voltage (VCHA). When an abnormal charge current flows into a battery in the
overdischarge status, the S-8241 consequently turns the charging control FET off and stops charging after the battery
voltage becomes the overdischarge detection voltage or higher (DO pin voltage becomes “H”) and the overcharge
detection delay time (tCU) elapses.
Abnormal charge current detection is released when the voltage difference between VM pin and VSS pin becomes
lower than the charger detection voltage (VCHA) by separating the charger.
Since the 0 V battery charging function has higher priority than the abnormal charge current detection function,
abnormal charge current may not be detected by the product with the 0 V battery charging function while the battery
voltage is low.
7. Delay Circuits
The detection delay times are determined by dividing a clock of approximately 2 kHz by the counter.
[Example] Overcharge detection delay time (= abnormal charge current detection delay time): 1.0 s
Overdischarge detection delay time: 125 ms
Overcurrent 1 detection delay time: 8 ms
Overcurrent 2 detection delay time: 2 ms
Caution 1. Counting for the overcurrent 2 detection delay time starts when the overcurrent 1 is detected.
Having detected the overcurrent 1, if the overcurrent 2 is detected after the overcurrent 2 detection
delay time, the S-8241 Series turns the discharging control FET off as shown in the Figure 6. In
this case, the overcurrent 2 detection delay time may seem to be longer or overcurrent 1 detection
delay time may seem to be shorter than expected.

2. <For products with power-down function>
After having detected an overcurrent (overcurrent 1, overcurrent 2, short-circuiting), the state is
held for the overdischarge detection delay time or longer without releasing the load, the status
changes to the power-down status when the battery voltage drops below the overdischarge
detection voltage. If the battery voltage drops below the overdischarge detection voltage due to
overcurrent, the discharging control FET is turned off when the overcurrent is detected. If the
battery voltage recovers slowly and if the battery voltage after the overdischarge detection delay
time is equal to or lower than the overdischarge detection voltage, the S-8241 changes to the
power-down status.
<For products without power-down function>
After having detected an overcurrent (overcurrent 1, overcurrent 2, short-circuiting), the state is
held for the overdischarge detection delay time or longer without releasing the load, the status
changes to the overdischarge status when the battery voltage drops below the overdischarge
detection voltage. If the battery voltage drops below the overdischarge detection voltage due to
overcurrent, the discharging control FET is turned off when the overcurrent is detected. If the
battery voltage recovers slowly and if the battery voltage after the overdischarge detection delay
time is equal to or lower than the overdischarge detection voltage, the S-8241 changes to the
overdischarge status.
8. 0 V Battery Charging Function
This function enables the charging of a connected battery whose voltage is 0 V by self-discharge. When a charger
having 0 V battery start charging charger voltage (V0CHA) or higher is connected between EB+ and EB- pins, the
charging control FET gate is fixed to VDD potential. When the voltage between the gate and the source of the charging
control FET becomes equal to or higher than the turn-on voltage by the charger voltage, the charging control FET is
turned on to start charging. At this time, the discharging control FET is off and the charging current flows through the
internal parasitic diode in the discharging control FET. If the battery voltage becomes equal to or higher than the
overdischarge release voltage (VDU), the normal status returns.
Caution 1. Some battery providers do not recommend charging of completely discharged batteries. Please
refer to battery providers before the selection of 0 V battery charging function.
2. The 0 V battery charging function has higher priority than the abnormal charge current detection
function. Consequently, a product with the 0 V battery charging function charges a battery and
abnormal charge current cannot be detected during the battery voltage is low (at most 1.8 V or
lower).
3. When a battery is connected to the IC for the first time, the IC may not enter the normal status in
which discharging is possible. In this case, set the VM pin voltage equal to the VSS voltage (short
the VM and VSS pins or connect a charger) to enter the normal status.
9. 0 V Battery Charge Inhibiting Function
This function forbids the charging of a connected battery which is short-circuited internally (0 V battery). When the
battery voltage becomes 0.9 V (typ.) or lower, the charging control FET gate is fixed to EB- potential to forbid charging.
Charging can be performed, when the battery voltage is the 0 V battery charge inhibiting voltage (V0INH) or higher.
Caution 1. Some battery providers do not recommend charging of completely discharged batteries. Please
refer to battery providers before the selection of 0 V battery charging function.
2. When a battery is connected to the IC for the first time, the IC may not enter the normal status in
which discharging is possible. In this case, set the VM pin voltage equal to the VSS voltage (short
the VM and VSS pins or connect a charger) to enter the normal status.

*1.
If an FET with a threshold voltage of 0.4 V or lower is used, the FET may fail to cut the charging current.
If an FET with a threshold voltage equal to or higher than the overdischarge detection voltage is used, discharging may stop
before overdischarge is detected.
*2.
If the withstand voltage between the gate and source is lower than the charger voltage, the FET may break.
*3.
If R1 has a higher resistance than R2 and if a charger is connected reversely, current flows from the charger to the IC and the
voltage between VDD and VSS may exceed the absolute maximum rating. Install a resistor of 300
or higher as R1 for ESD
protection.
If R1 has a high resistance, the overcharge detection voltage increases by IC current consumption.
*4.
If a capacitor C1 is less than 0.01
F, DO may oscillate when load short-circuiting is detected, a charger is connected
reversely, or overcurrent 1 or 2 is detected.
A capacitor of 0.01
F or higher as C1 should be installed. In some types of batteries DO oscillation may not stop unless the
C1 capacity is increased. Set the C1 capacity by evaluating the actual application.
*5.
If R2 is set to less than 300
, a current which is bigger than the power dissipation flows through the IC and the IC may break
when a charger is connected reversely. If a resistor bigger than 1.3 k
is installed as R2, the charging current may not be cut
when a high-voltage charger is connected.
Caution 1. The above constants may be changed without 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 constant do not guarantee
proper operation. Perform thorough evaluation using the
actual application to set the constant.
