The S-8259A Series is an IC including high-accuracy voltage detection circuits and delay circuits. The S-8259A Series is suitable for monitoring overcharge and overdischarge for 1-cell lithium-ion / lithium polymer rechargeable battery packs.
Features
High-accuracy voltage detection circuit
Overcharge detection voltage: 3.500 V to 4.600 V (5 mV step) Accuracy ±20 mV
Overcharge release voltage: 3.100 V to 4.600 V*1 Accuracy ±50 mV
Overdischarge detection voltage: 2.000 V to 3.400 V (10 mV step) Accuracy ±50 mV
Overdischarge release voltage 2.000 V to 3.400 V*2 Accuracy ±100 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage can be selected from a range of 0 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 from a range of 0.1 V to 0.7 V in 100 mV step.)
Applications
Lithium-ion rechargeable battery pack
Lithium polymer rechargeable battery pack
