BATTERY PROTECTION IC FOR 1-SERIAL TO 4-SERIAL-CELL PACK
(SECONDARY PROTECTION)
Seiko Instruments Inc., 2003-2010
Rev.6.0_00
Seiko Instruments Inc.
1
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-circuits between cells accommodate series 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 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
(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
*1. Refer to “
Product Name Structure” for details.
Applications
Lithium ion rechargeable battery packs (secondary protection)
Packages
