OVERCURRENT MONITORING IC
FOR MULTI-SERIAL-CELL PACK
Rev.1.1_04
The S-8239B Series is an overcurrent monitoring IC for multi-serial-cell pack including high-accuracy voltage detection
circuits and delay circuits.
The S-8239B 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 is selectable: 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 A max.
During power-down:
0.1 A max.
Output logic:
Active "L"
Wide operation temperature range:
Ta = 40C to 85C
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.
