General Description

The EC9523 Li-ion/Li-polymer battery protection IC has high accuracy voltage detector and delay time circuit in
side.0 V charge function and self-recovery function are available. The operating quiescent current is very low.
It is designed to protect 1-cell lithium-ion / lithium polymer rechargeable batteries from damage or degrading life time due to the overcharge, over discharge and charge/discharge over current etc.

Features

◆ Overcharge detection voltage 4.25 V to 4.35V, Accuracy ±50 mV
◆ Overcharge release voltage 4.05 V to 4.15V, Accuracy ±50 mV
◆ Overdischarge detection voltage 2.3 to 2.5V, Accuracy 100 mV
◆ Overdischarge release voltage 2.9 to 3.1V, Accuracy ± 100 mV
◆ Ultra-low operating current 2.5μA@Vcc=3.9V
◆ Self-recovery function available
◆ Overcurrent protection and load short protection
◆ 0V charge function available
◆ Over charge current protection available

Applications

◆ Single cell Lithium-ion/Lithium polymer rechargeable battery pack.
