一,产品概述(General Description)         
      The CXPR7144I product is a highintegration solution for lithium-ion/polymer 

battery protection.
      CXPR7144I contains advanced power MOSFET, high-accuracy voltage detection

 circuits and delay circuits.
      CXPR7144I is put into an ultra-small DFN2X2-6 package and only one external component makes it an idealsolution in limited space of battery pack.
      CXPR7144I 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 long-
term battery life.
