LITHIUM-ION BATTERY PROTECTION IC (FOR 3-CELL)
S-8233A/B/C Series
The S-8233A Series is a series of lithium-ion rechargeable
FEATURES
battery protection ICs incorporating high-accuracy voltage
detectors and a delay circuit. This series is suitable for
protecting a three-cell pack.
• Internal high-accuracy voltage detection circuit
•
Over charge detection voltage
4.10 ± 0.05 V to 4.35 ± 0.05 V
0.05 V - step
•
•
Accuracy of over charge detection voltage ± 25mV (B Series)
Over charge release voltage
3.85 ± 0.10 V to 4.35 ± 0.10 V
PIN CONFIGURATIONS
0.05 V - step
(The over charge release voltage can be selected within the range where
a difference from over charge detection voltage is 0 to 0.3 V)
Over discharge detection voltage 2.00 ± 0.08 V to 2.70 ± 0.08 V
0.10 V - step
