BATTERY MONITORING IC FOR 1-CELL PACK
Rev.1.1_01
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
Overcharge release voltage
3.500 V to 4.600 V (5 mV step)
3.100 V to 4.600 V*1
Accuracy 20 mV
Accuracy 50 mV
Overdischarge detection voltage
Overdischarge release voltage
2.000 V to 3.400 V (10 mV step)
2.000 V to 3.400 V*2
Accuracy 50 mV
Accuracy 100 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
CO pin output logic is selectable:
Active "H", active "L"
Wide operation temperature range:
Ta = 40°C to 85°C
Low current consumption
During operation:
1.5 A typ., 3.0 A max. (Ta = 25°C)
During overdischarge:
2.0 A 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 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
Package
SOT-23-6
