BATTERY PROTECTION IC
FOR 3-SERIAL-CELL PACK
S-8233B Series
The S-8233B is a series of lithium-ion rechargeable battery protection ICs
incorporating high-accuracy (±25 mV) voltage detection circuits and delay
circuits. It is suitable for a 3-serial-cell lithium-ion battery pack.
„ Features
(1) Internal high-accuracy voltage detection circuit
• Over charge detection voltage
3.80 ± 0.025 V to 4.40 ± 0.025 V
5 mV - step
• Over charge release voltage
3.45 ± 0.100 V to 4.40 ± 0.100 V
5 mV - step
(The over charge release voltage can be selected within the range where a difference from over
charge detection voltage is 0 to 0.35 V with 50 mV - step)
• Over discharge detection voltage
2.00 ± 0.08 V to 2.80 ± 0.08 V
50 mV - step
ΠOver discharge release voltage
2.00 ± 0.10 V to4.00 ± 0.10 V
50 mV - step
(The over discharge release voltage can be selected within the range where a difference from over
discharge detection voltage is 0 to 1.2 V with 50 mV - step)
• Over current detection voltage 1
0.15 ± 0.015 V to 0.5 ± 0.05 V
50 mV - step
(2) High input-voltage device (absolute maximum rating: 26 V)
(3) Wide operating voltage range:
2 V to 24 V
(4) The delay time for every detection can be set via an external capacitor.
(5) Three over current detection levels (protection for short-circuiting)
(6) Internal charge/discharge prohibition circuit via the control terminal
(7) The function for charging batteries from 0 V is available.
(8) Low current consumption
