S-8239A Series

OVERCURRENT MONITORING IC

FOR MULTI-SERIAL-CELL PACK

www.sii-ic.com

Rev.1.4_03

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

Overcurrent 2 detection voltage

Overcurrent 3 detection voltage

0.04 V to 0.30 V (10 mV step)

0.1 V to 0.7 V (100 mV step)

1.2 V (Fixed)

Accuracy 15 mV

Accuracy 100 mV

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 μA max.

During UVLO operation:

6.0 μA max.

• Output logic:

Active "L", Active "H"

• Wide operation temperature range:

• Lead-free (Sn 100%), halogen-free

Ta = −40°C to +85°C

*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

 Package

• SOT-23-6
