BATTERY PROTECTION IC
FOR 1-CELL PACK
Rev.6.5_02
The S-8211D Series is a protection IC for 1-cell lithium-ion / lithium-polymer rechargeable battery and includes high-accuracy
voltage detection circuits and delay circuits.
The S-8211D Series is suitable for protecting 1-cell rechargeable lithium-ion / lithium-polymer battery packs from overcharge,
overdischarge, and overcurrent.
 Features

• 0 V battery charge function "available" / "unavailable" is selectable.
• Power-down function "available" / "unavailable" is selectable.
• Wide operation temperature range
Ta = −40°C to +85°C
• Low current consumption
During operation
3.0 μA typ., 5.5 μA max. (Ta = +25°C)
During power-down

• Lead-free, Sn 100%, halogen-free^*3
*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
