The S-8232 series is suitable for 2-cell serial lithium-ion / lithium-polymer battery packs.
Features
(1) Internal high-accuracy voltage detection circuit
• Overcharge detection voltage 3.85 V ± 25 mV to 4.60 V ± 25 mV Applicable in 5 mV step
• Overcharge release voltage 3.60 V ± 50 mV to 4.60 V ± 50 mV Applicable in 5 mV step
(The overcharge release voltage can be selected within the range where a difference from overcharge
detection voltage is 0 V to 0.3 V.)
• Overdischarge detection voltage 1.70 V ± 80 mV to 2.60 V ± 80 mV Applicable in 50 mV step
• Overdischarge release voltage 1.70 V ± 100 mV to 3.80 V ± 100 mV Applicable in 50 mV step
(The overdischarge release voltage can be selected within the range where a difference from
overdischarge detection voltage is 0 V to 1.2 V.)
• Overcurrent detection voltage 1 0.07 V ± 20 mV to 0.30 V ± 20 mV Applicable in 5 mV step
(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.
(Each delay time for Overcharge detection, Overdischarge detection, Overcurrent detection are
“Proportion of hundred to ten to one”.)
(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
• Operation mode 7.5 μA typ. 14.2 μA max. (− 40°C to + 85°C)
• Power-down mode 0.2 nA typ. 0.1 μA max. (− 40°C to + 85°C)
(9) Lead-free, Sn100%, halogen-free *1
*1. Refer to “ Product Name Structure” for details.
