Rev.2.6_00
The S-8240A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy
voltage detection circuits and delay circuits.
The S-8240A Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge,
overdischarge, and overcurrent.

3.500 V to 4.600 V (5 mV step)
3.100 V to 4.600 V*1
Accuracy 20 mV
Accuracy 50 mV
Overdischarge detection voltage
Overdischarge release voltage
2.000 V to 3.400 V (10 mV step)
2.000 V to 3.400 V*2
Accuracy 50 mV
Accuracy 100 mV
Discharge overcurrent detection voltage
Load short-circuiting detection voltage
0.015 V to 0.200 V (5 mV step)
0.065 V to 0.500 V (25 mV step)*3
Accuracy 5 mV
Accuracy 40 mV
Charge overcurrent detection voltage
0.200 V to 0.015 V (5 mV step) Accuracy 5 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
0 V battery charge function is selectable:
Available, unavailable
Power-down function is selectable:
Available, unavailable
Release condition of discharge overcurrent status is selectable:
Load disconnection, charger connection
Release voltage of discharge overcurrent status is selectable:
VRIOV, VDIOV
High-withstand voltage:
VM pin and CO pin: Absolute maximum rating 28 V
Wide operation temperature range:
Ta = 40°C to 85°C
Low current consumption
During operation:
1.5 A typ., 3.0 A max. (Ta = 25°C)
During power-down:
50 nA max. (Ta = 25°C)
During overdischarge:
500 nA max. (Ta = 25°C)
Lead-free (Sn 100%), halogen-free
*1. Overcharge release voltage = Overcharge detection voltage Overcharge hysteresis voltage
(Overcharge hysteresis voltage can be selected from a range of 0 V to 0.4 V in 50 mV step.)
*2. Overdischarge release voltage = Overdischarge detection voltage Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage can be selected from a range of 0 V to 0.7 V in 100 mV step.)
*3. Load short-circuiting detection voltage = Discharge overcurrent detection voltage 0.025 n
(n can be selected from any integer value greater or equal to 2)
