BATTERY PROTECTION IC FOR 1-CELL PACK
Rev.1.0_00
The S-8240B Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy
voltage detection circuits and delay circuits.
The S-8240B Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge,
overdischarge, and overcurrent.

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 μA typ., 3.0 μA 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)
