The S-8232 series is a lithium-ion / lithium-polymer rechargeable battery protection IC incorporating high-
accuracy voltage detection circuit and delay circuit.
The S-8232 series is suitable for 2-cell serial lithium-ion / lithium-polymer battery packs.
(1) Internal high-accuracy voltage detection circuit
(2) High input-voltage device : Absolute maximum ratings 18 V.
(3) Wide operating voltage range : 2.0 V to 16 V
(4) The delay time for every detection can be set via an external capacitor.
(5) Two overcurrent detection levels (Protection for short-circuiting)
(6) Internal auxiliary over voltage detection circuit (Fail-safe for overcharge detection voltage)
(7) Internal charge circuit for 0 V battery (Unavailable is option)
(8) Low current consumption
(9) Lead-free, Sn100%, halogen-free
• Lithium-ion rechargeable battery packs

• Operation mode
• Power-down mode 0.2 nA typ. 0.1 μA max. (− 40°C to + 85°C)
(Each delay time for Overcharge detection, Overdischarge detection, Overcurrent detection are
“Proportion of hundred to ten to one”.)
(The overcharge release voltage can be selected within the range where a difference from overcharge
detection voltage is 0 V to 0.3 V.)
(The overdischarge release voltage can be selected within the range where a difference from
overdischarge detection voltage is 0 V to 1.2 V.)
