S-8243A/B Series

BATTERY PROTECTION IC

FOR 3-SERIAL OR 4-SERIAL CELL PACK

www.sii-ic.com

Rev.3.1_00

The S-8243A/B Series is a protection IC for lithium-ion rechargeable battery. The S-8243A Series protects 3-series, the S-8243B

Series protects 4-series cell pack from the overcharge, overdischarge, overcurrent voltages. This IC has a high-accuracy battery

protection circuit and a battery monitor amplifier, and also a voltage regulator which operates the microcomputer or gas gauge IC.

Combining this IC and a microcomputer or a gas gauge IC allows to display the amount of charge remained in a battery.

 Features

(1) High-accuracy voltage detection for each cell

• Overcharge detection voltage n (n = 1 to 4)

3.9 V to 4.4 V (50 mV step)

• Overcharge hysteresis voltage n (n = 1 to 4) of overcharge detection

−0.10 V to −0.40 V (50 mV step) or 0 V

Accuracy 25 mV

Accuracy 50 mV

(Overcharge release voltage n (= Overcharge detection voltage n + Overcharge hysteresis voltage n) can be

selected within the range 3.8 V to 4.4 V.)

• Overdischarge detection voltage n (n = 1 to 4)

2.0 V to 3.0 V (100 mV step)

• Overdischarge hysteresis voltage n (n = 1 to 4) of overdischarge detection

0.15 V to 0.70 V or 0 V (50 mV step)

Accuracy 80 mV

Accuracy 100 mV

(Overdischarge release voltage n (

= Overdischarge detection voltage n + Overdischarge hysteresis voltage n)

can be selected within the range 2.0 V to 3.4 V.)

(2) Three-level overcurrent protection including protection for short-circuiting

• Overcurrent detection voltage 1

• Overcurrent detection voltage 2

• Overcurrent detection voltage 3

0.05 V to 0.3 V (50 mV step)

0.5 V

Accuracy 25 mV

Accuracy 100 mV

Accuracy 15 %

V_DD/ 2

(3) Delay times for overcharge detection, overdischarge detection and overcurrent detection 1 can be set by external

capacitors. (Delay times for overcurrent detection 2 and 3 are fixed internally.)

(4) Charge/discharge operation can be controlled through the control pins.

(5) High-accuracy battery monitor amp

(6) Voltage regulator

GAMP = V_BATTERY× 0.2 1.0%

_OUT= 3.3 V 2.4 % (3 mA max.)

(7) High-withstand voltage

(8) Wide operating voltage range

(9) Wide operating temperature range:

(10) Low current consumption

• Operation mode

Absolute maximum rating: 26 V

6 V to 18 V

−40°C to +85°C

120 μA max.

0.1 μA max.

• Power down mode

(11) Lead-free, Sn 100%, halogen-free^*1

*1. Refer to “ Product Name Structure” for details.

 Applications

• Lithium-ion rechargeable battery packs

• Lithium polymer rechargeable battery packs

 Package

• 16-Pin TSSOP
