一,产品概述(General Description)         qSp嘉泰姆
    The CXPR7149 product is a high integration solution for lithium-ion/polymer qSp嘉泰姆

battery protection. CXPR7149 contains advanced power MOSFET, high-accuracy qSp嘉泰姆

voltage detection circuits and delay circuits.qSp嘉泰姆

    CXPR7149 is put into an ultra-small SOT23-5 package and only one external qSp嘉泰姆

component makes it an ideal solution in limited space of battery pack.qSp嘉泰姆
   CXPR7149 has all the protection functions required in the battery application qSp嘉泰姆

including overcharging, overdischarging, overcurrent and load short circuiting qSp嘉泰姆

protection etc. The accurate overcharging detection voltage ensures safe and qSp嘉泰姆

full utilization charging.qSp嘉泰姆
     The low standby current drains little current  from the cell while in storage.qSp嘉泰姆
The device is not only targeted for digital cellular phones, but also for any otherqSp嘉泰姆
Li-Ion and Li-Poly battery-powered information appliances requiring long-term qSp嘉泰姆

battery life.qSp嘉泰姆
