Power Management ICs

Battery Protection IC for 1-Cell Pack S-8200A Series

The S-8200A 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.


High-accuracy voltage detection circuit
Overcharge detection voltage 3.5 V to 4.5 V (5 mV steps)
Accuracy ±20 mV (+25°C) Accuracy ±25 mV (-10°C to +60°C)
Overcharge release voltage 3.1 V to 4.5 V*1 Accuracy ±30 mV
Overdischarge detection voltage 2.0 V to 3.4 V (10 mV steps) Accuracy ±35 mV
Overdischarge release voltage 2.0 V to 3.4 V*2 Accuracy ±50 mV
Discharge overcurrent detection voltage 0.05 V to 0.20 V (10 mV steps) Accuracy ±10 mV
Load short-circuiting detection voltage 0.5 V (fixed) Accuracy ±100 mV
Charge overcurrent detection voltage -0.20 V to -0.05 V (25 mV steps) Accuracy ±15 mV
Detection delay times are generated by an internal circuit (external capacitors are unnecessary). Accuracy ±20%
High-withstand voltage (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 operating temperature range
Ta = -40°C to +85°C
Low current consumption
During operation: 2.8 µA typ.,5.0 µA max. (Ta = +25°C)
During power-down: 0.1 µA 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 as 0 V or from a range of 0.1 V 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 V to 0.7 V in 100 mV steps.)
