BATTERY PROTECTION IC

FOR 2-SERIAL-CELL PACK

Rev.2.3

_01

The S-8242B Series are protection ICs for 2-serial-cell lithium-ion/lithium polymer rechargeable batteries and include high-

accuracy voltage detectors and delay circuits.

These ICs are suitable for protecting 2-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge,

overdischarge, and overcurrent.

Features

(1)

High-accuracy voltage detection for each cell

•

Overcharge detection voltage n (n

1, 2)

3.9 V to 4.5 V (50 mV steps)

Accuracy

±25

Accuracy

±50

•

Overcharge release voltage n (n

1, 2)

3.8 V to 4.5 V

•

Overdischarge detection voltage n (n

1, 2)

2.0 V to 3.0 V (100 mV steps)

Accuracy

±50

Accuracy

±100

•

Overdischarge release voltage n (n

1, 2)

2.0 V to 3.4 V

Two-level overcurrent detection (overcurrent 1, overcurrent 2)

•

Overcurrent detection voltage 1

0.05 V, 0.08 V to 0.30 V (10 mV steps)

Accuracy

±15

•

Overcurrent detection voltage 2

1.2 V (fixed)

Accuracy

±300

Delay times (overcharge, overdischarge, overcurrent) are generated by an internal circuit (external capacitors are

unnecessary).

0 V battery charge function available/unavailable are selectable.

Charger detection function

•

The overdischarge hysteresis is released by detecting negative voltage at the VM pin (−0.7 V typ.) (Charger

detection function).

High-withstand voltage devices

Absolute maximum rating: 28 V

Wide operating temperature range

−40°C

+85°C

Low current consumption

Operation mode

μA

max. (+25°C)

Power-down mode

0.1

μA

max. (+25°C)

Lead-free, Sn 100%, halogen-free
