S-8239A

S-8239A Series www.ablic.com © ABLIC Inc., 2013-2020 OVERCURRENT MONITORING IC FOR MULTI-SERIAL-CELL PACK Rev.1.6_00 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 v...
