BATTERY PROTECTION IC FOR 1-SERIAL TO 4-SERIAL-CELL PACK

(SECONDARY PROTECTION)

Rev.6.2

_00

The S-8244 Series is used for secondary protection of lithium-ion batteries with from one to four cells, and incorporates a

high-precision voltage detector circuit and a delay circuit. Short-circuiting between cells makes it possible for serial

connection of one to four cells.

Features

(1) Internal high-precision voltage detector circuit

•

Overcharge detection voltage range : 3.700 V to 4.500 V : Accuracy of

25 mV (at

+25°C)

(at a 5 mV/step)

Accuracy of

50 mV (at

−40°C

+85°C)

•

Hysteresis :

5 types

0.38

0.1 V, 0.25

0.07 V, 0.13

0.04 V, 0.045

0.02 V, None

(2) High withstand voltage device :

Absolute maximum rating : 26 V

(3) Wide operating voltage range :

3.6 V to 24 V (refers to the range in which the delay circuit can operate

normally after overvoltage is detected)

(4) Delay time during detection :

Can be set by an external capacitor.

(5) Low current consumption :

At 3.5 V for each cell : 3.0

μA

max. (+25°C)

At 2.3 V for each cell : 2.4

μA

max. (+25°C)

(6) Output logic and form :

5 types

CMOS output active “H”

CMOS output active “L”

Pch open drain output active “L”

Nch open drain output active “H”

Nch open drain output active “L”

(CMOS / Nch open drain output for 0.045 V hysteresis models)

(7) Lead-free, Sn 100%, halogen-free

*1.
