BATTERY PROTECTION IC FOR 1-CELL PACK
Rev.2.0_00
The S-82A1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy
voltage detection circuits and delay circuits. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery
packs from overcharge, overdischarge, and overcurrent.
By using an external overcurrent detection resistor, the S-82A1A Series realizes high-accuracy overcurrent protection with less
effect from temperature change.

• 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:
2.0 μA typ., 4.0 μA max. (Ta = +25°C)
During power-down:
50 nA max. (Ta = +25°C)
During overdischarge:
• Lead-free, Sn 100%, halogen-free*3
P
500 nA max. (Ta = +25°C)
*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 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 as 0 V or from a range of 0.1 V to 0.7 V in 100 mV step.)
*3. Refer to " Product Name Structure" for details.
Applications
• Lithium-ion rechargeable battery pack
• Lithium polymer rechargeable battery pack
Packages
• SNT-6A
• DFN-6(1414)A
