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

battery protection.vIY嘉泰姆
      CXPR7144I contains advanced power MOSFET, high-accuracy voltage detectionvIY嘉泰姆

 circuits and delay circuits.vIY嘉泰姆
      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.vIY嘉泰姆
      CXPR7144I has all the protection functions required in the battery application vIY嘉泰姆

including  overcharging, overdischarging, overcurrent and load short circuiting protection etc. The accurate overcharging detection voltage ensures safe and full utilization charging.vIY嘉泰姆
     The low standby current drains little current  from the cell while in storage.vIY嘉泰姆
     The device is not only targeted for digital cellular phones, but also for any othervIY嘉泰姆
Li-Ion and Li-Poly battery-powered information appliances requiring long-vIY嘉泰姆
