Description

The 8232 Series are lithium-ion / lithium-polymer rechargeable batteries protection ICs incorporating highaccuracy voltage detection circuits and delay circuits.
The S-8232 Series are suitable for 2-cell serial lithiumion / lithium-polymer battery packs.

Features

(1) Internal high-accuracy voltage detection circuit
• Overcharge detection voltage 3.90 V ¡À 25 mV to 4.60 V ¡À 25 mV Applicable in 5 mV step
• Overcharge release voltage 3.60 V ¡À 50 mV to 4.60 V ¡À 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 to 0.3 V.)
• Overdischarge detection voltage 1.70 V ¡À 80 mV to 2.60 V ¡À 80 mV Applicable in 50 mV step
• Overdischarge release voltage 1.70 V ¡À 100 mV to 3.80 V ¡À 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 to 1.2 V.)
• Overcurrent detection voltage 1 0.07 V ¡À 20 mV to 0.30 V ¡À 20 mV Applicable in 5 mV step
(2) High input-voltage device : Absolute maximum ratings 18 V.
(3) Wide operating voltage range : 2 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 ¦ÌA typ. 14.2 ¦ÌA max. (− 40 to + 85 ¡ãC)
• Power-down mode 0.2 nA typ. 0.1 ¦ÌA max. (− 40 to + 85 ¡ãC)
(9) Lead-free products
􀂄
Application

• Lithium-ion rechargeable battery packs
