BATTERY PROTECTION IC FOR 1-SERIAL TO 4-SERIAL-CELL PACK
(SECONDARY PROTECTION)
Rev.6.5
_01
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
(2) High-withstand voltage:
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
A
max. (25C)
At 2.3 V for each cell: 2.4
A
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)
*1
(7) Lead-free, Sn 100%, halogen-free
*1.
