东莞XR7608AJ（锂电池保护IC）

一、GENERAL DESCRIPTION 

The XR7608AJ series product is a high integration solution for lithiumion/polymer battery protection. XR7608AJ contains advanced power MOSFET, highaccuracy voltage detection circuits and delay circuits. XR7608AJ is put into an ultra-small CPC5 package and only one external component makes it an ideal solution in limited space of battery pack. 

XR7608AJ has all the protection functions required in the battery application including overcharging, overdischarging, overcurrent and load short circuiting protection etc. The accurate overcharging detection voltage 

ensures safe and full utilization charging. The low standby current drains little current from the cell while in storage. The device is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring longterm battery life.
