S-8244 Series

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

(SECONDARY PROTECTION)

www.sii-ic.com

Rev.6.4_02

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 4.550 V: Accuracy of 25 mV (at +25°C)

(at a 5 mV/step)

Accuracy of 50 mV (at −40°C to +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

Absolute maximum rating: 26 V

(2) High-withstand voltage:

(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)

Can be set by an external capacitor.

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)

5 types

(4) Delay time during detection:

(5) Low current consumption:

(6) Output logic and form:

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

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

 Applications

• Lithium ion rechargeable battery packs (secondary protection)

 Packages

• SNT-8A

• 8-Pin MSOP

• TMSOP-8
