BATTRY PROTECTION IC

FOR 3-SERIAL OR 4-SERIAL CELL PACK

S-8243A/B Series

The S-8243A/B is a series of lithium-ion rechargeable

battery protection ICs incorporating high-accuracy

battery protection circuits, a battery monitor amp and a

voltage regulator which drives microcomputer and gas

gauge IC. Combining microcomputer or gas gauge IC

facilitates displaying a remaining amount of battery.

The S-8243A/B is suitable for protection of 3-serial or

4-serial cell lithium-ion battery packs from

overcharge, overdischarge and overcurrent.

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)

Accuracy ±25 mV

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

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

Accuracy ±50 mV

(Overcharge release voltage n (=Overcharge detection voltage n + 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)

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

0.20 V to 0.70 V or 0 V (100 mV step)

Accuracy ±80 mV

Accuracy ±100 mV

(Overdischarge release voltage n (=Overdischarge detection voltage n + 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) Accuracy ±25 mV

0.5 V

V_DD/2

Accuracy ±100 mV

Accuracy ±15 %

(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%

V_OUT= 3.3 V ±2.4 % (3 mA max.)

Absolute maximum rating: 26 V

6 V to 18 V

(7) High input-voltage device

(8) Wide operating voltage range

(9) Wide operating temperature range:

(10) Low current consumption

Operation mode

−40°C to +85 °C

120 μA max.

Power down mode

0.1 μA max.

(11) Small package

16-Pin TSSOP package

(12) Lead-free products

Applications

• Lithium-ion rechargeable battery packs

• Lithium polymer rechargeable battery packs
