The S-8239A Series is an overcurrent monitoring IC for multi-serial-cell pack including high-accuracy voltage detection circuits and delay circuits. The S-8239A Series is suitable for protection of lithium-ion / lithium polymer rechargeable battery packs from overcurrent.
Features
Built-in high-accuracy voltage detection circuit
Overcurrent 1 detection voltage*1 : 0.04 V to 0.30 V (10 mV step) : Accuracy ±15 mV
Overcurrent 2 detection voltage : 0.1 V to 0.7 V (100 mV step) : Accuracy ±100 mV
Overcurrent 3 detection voltage : 1.2 V (Fixed) : Accuracy ±300 mV
Built-in three-step overcurrent detection circuit
Overcurrent 1, overcurrent 2, overcurrent 3
Overcurrent 3 detection function
Available, unavailable
UVLO (under voltage lock out) function
UVLO detection voltage : 2.0 V (Fixed) : Accuracy ±100 mV
High-withstand voltage
VM pin, DO pin: Absolute maximum rating 28 V
Delay times are generated only by an internal circuit (External capacitors are unnecessary).
Low current consumption
During normal operation: 7.0 μA max.
During UVLO operation: 6.0 μA max.
Output logic
Active “L”, Active “H”
Wide operation temperature range
Ta = −40°C to +85°C
Lead-free (Sn 100%), halogen-free
*1. Overcurrent 1 detection voltage ≤ 0.06 V should be satisfied in the case of overcurrent 2 detection voltage = 0.1 V. Overcurrent 1 detection voltage ≤ 0.85 × overcurrent 2 detection voltage − 0.05 V should be satisfied in the case of overcurrent 2 detection voltage ≥ 0.2 V.
Applications
Lithium-ion rechargeable battery pack
Lithium polymer rechargeable battery pack
