The S-8264A/B/C Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates a
high-accuracy voltage detection circuit and a delay circuit.
Short-circuiting between cells makes it possible for serial connection of two cells to four cells.
Features
High-accuracy voltage detection circuit for each cell
•
Overcharge detection voltage n (n
=
1 to 4)
4.200 V to 4.800 V (in 50 mV steps) Accuracy :
±25
mV (+25°C), Accuracy :
±30
mV (−5°C to
+55°C)
•
Overcharge hysteresis voltage n (n
=
1 to 4)

(2) Delay times for overcharge detection can be set by an internal circuit only (external capacitors are unnecessary)
(3) Output control function via CTL pin (CTL pin is pulled down internally) (S-8264A Series)
Output control function via CTL pin (CTL pin is pulled up internally) (S-8264C Series)
(4) Output latch function after overcharge detection (S-8264B Series)
(5) Output form and logic
CMOS output active “H”
(6) High withstand voltage
Absolute maximum rating 26 V
(7) Wide operation voltage range
3.6 V to 24 V
(8) Wide operation temperature range
