BATTERY PROTECTION IC (FOR A 3-SERIAL-CELL PACK)
The 8233A is a series of lithium-ion rechargeable battery protection ICs incorporating high-accuracy voltage detection circuits and delay circuits. It is suitable for a 3-serial-cell lithium-ion battery pack.
(1) 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
Over charge release voltage 3.85 ± 0.10 V to 4.35 ± 0.10 V 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
Over discharge release voltage 2.00 ± 0.10 V to3.70± 0.10 V 0.10 V - step
(The over discharge release voltage can be selected within the range where a difference from over discharge detection voltage is 0 to 1.0V)
Over current detection voltage 1 0.15 V±10% to 0.50 V±10% 0.05 V-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.
Power-down 0.1 ?A max (+25 °C)
