BATTERY MONITORING IC FOR 1-CELL PACK
Rev.1.0_02
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
3.5 V to 4.6 V (5 mV step)
Accuracy ±20 mV
Overcharge release voltage
3.1 V to 4.6 V^*1
Accuracy ±50 mV
Overdischarge detection voltage
2.0 V to 3.4 V (10 mV step)
Accuracy ±50 mV
Overdischarge release voltage
2.0 V to 3.4 V^*2
Accuracy ±100 mV
• Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
• Wide operation temperature range:
Ta = −40°C to +85°C
• Low current consumption
During operation:
1.5 μA typ., 3.0 μA max. (Ta = +25°C)
During overdischarge:
2.0 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 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
