BATTERY PROTECTION IC
FOR 3-SERIAL-CELL PACK
S-8233C Series
The S-8233C Series is a series of lithium-ion rechargeable battery
protection ICs incorporating high-accuracy voltage detection circuits and
delay circuits.
The S-8233C series includes the function to measure the status of
battery pack.
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 ± 0.05 V to 4.40 ± 0.05 V
5 mV - step
Over charge release voltage
3.45 ± 0.10 V to 4.40 ± 0.10 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 at 50 mV - Step)
Over discharge detection voltage
2.00 ± 0.08 V to 2.80± 0.08 V
50 mV - step
Over discharge release voltage
2.00 ± 0.10 V to 4.00± 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 at 50 mV - Step)
Over current detection voltage 1
0.15 ±0.015 V to 0.50 ±0.05 V
50 mV - step
(2) High input-voltage device (absolute maximum rating: 26 V)
(3) Indicates Li-ion battery state.
(4) Wide operating voltage range:
2 V to 24 V
(5) The delay time for every detection can be set via an external capacitor.
(6) Three over current detection levels (protection for short-circuiting)
(7) Internal charge/discharge prohibition circuit via the control terminal
(8) The function for charging batteries from 0 V is available.
(9) Low current consumption
Operation
50 µA max. (+25 °C)
Power-down
0.1 µA max. (+25 °C)
(10) Lead-free products
Applications
Lithium-ion rechargeable battery packs
