BATTERY PROTECTION IC
FOR 1-CELL PACK
S-8211C Series
The S-8211C Series are protection ICs for single-cell lithium-ion /
lithium polymer rechargeable batteries and include high-accuracy
voltage detectors and delay circuits.
These ICs are suitable for protecting single-cell rechargeable
lithium-ion / lithium polymer battery packs from overcharge,
overdischarge, and overcurrent.
„ Features
(1) High-accuracy voltage detection circuit
• Overcharge detection voltage
3.9 to 4.4 V (5 mV steps)
Accuracy ±25 mV (+25 °C)
• Overcharge release voltage
3.8 to 4.4 V^*1
Accuracy ±30 mV (−5 to +55 °C)
Accuracy ±50 mV
• Overdischarge detection voltage
• Overdischarge release voltage
2.0 to 3.0 V (10 mV steps)
2.0 to 3.4 V^*2
Accuracy ±50 mV
Accuracy ±100 mV
• Discharge overcurrent detection voltage
0.05 to 0.30 V (10 mV steps) Accuracy ±15 mV
• Load short-circuiting detection voltage
0.5 V (fixed)
Accuracy ±200 mV
• Charge overcurrent detection voltage
−0.1 V (fixed)
Accuracy ±30 mV
(2) Detection delay times are generated by an internal circuit (external capacitors are unnecessary).
Accuracy ±20%
(3) High-withstanding-voltage device is used for charger connection pins
(VM pin and CO pin : Absolute maximum rating = 28 V)
(4) 0 V battery charge function available / unavailable are selectable.
(5) Wide operating temperature range
−40 to +85 °C
(6) Low current consumption
• Operation mode
3.0 µA typ., 5.5 µA max. (+25 °C)
• Power-down mode
0.2 µA max. (+25 °C)
(7) Small package
SOT-23-5, SNT-6A
(8) Lead-free product
*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 to 0.4 V in 50 mV steps.)
*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 to 0.7 V in 100 mV steps.)
„ Applications
