BATTERY PROTECTION IC
FOR 1-CELL PACK
Rev.6.5_00
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
• High-accuracy voltage detection circuit
Overcharge detection voltage
3.6 V to 4.5 V (5 mV step)
Accuracy ±25 mV (Ta = +25°C)
Overcharge release voltage
3.5 V to 4.4 V*1
Accuracy ±30 mV (Ta = −5°C to +55°C)
Accuracy ±50 mV
Overdischarge detection voltage
Overdischarge release voltage
2.0 V to 3.0 V (10 mV step)
2.0 V to 3.4 V*2
Accuracy ±50 mV
Accuracy ±100 mV
Discharge overcurrent detection voltage
0.05 V to 0.30 V (10 mV step) Accuracy ±15 mV
Load short-circuiting detection voltage
0.5 V (fixed)
Accuracy ±200 mV
• Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
Accuracy ±20%
• High-withstand voltage device is used for charger connection pins
(VM pin and CO pin: Absolute maximum rating = 28 V)
• 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
0.2 μA 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
• SOT-23-5
• SNT-6A
