Battery Monitoring IC for 1-cell Pack S-8259A Series

DatasheetAug. 09, 2019

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). 
CO pin output logic
Active “H”, active “L”
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
