EC9526A

One-cell Lithium Battery Protection IC

General Description

The EC9526A battery protection IC is designed to protect lithium-ion / polymer battery from damage or degrading

the lifetime due to over current for one-cell lithium-ion / polymer battery powered systems. such as cellular phones。

The ultra-small package and less required external components make it ideal to integrate the EC9526A into the

limited space of battery pack. The accurate ±50mV overcharging detection voltage ensures safe and full utilization

charging. The very low standby current drains little current from the cell while in storage。
