一,产品概述(General Description)         A1A嘉泰姆
    The CXPR7149 product is a high integration solution for lithium-ion/polymer A1A嘉泰姆

battery protection. CXPR7149 contains advanced power MOSFET, high-accuracy A1A嘉泰姆

voltage detection circuits and delay circuits.A1A嘉泰姆

    CXPR7149 is put into an ultra-small SOT23-5 package and only one external A1A嘉泰姆

component makes it an ideal solution in limited space of battery pack.A1A嘉泰姆
   CXPR7149 has all the protection functions required in the battery application A1A嘉泰姆

including overcharging, overdischarging, overcurrent and load short circuiting A1A嘉泰姆

protection etc. The accurate overcharging detection voltage ensures safe and A1A嘉泰姆

full utilization charging.A1A嘉泰姆
     The low standby current drains little current  from the cell while in storage.A1A嘉泰姆
The device is not only targeted for digital cellular phones, but also for any otherA1A嘉泰姆
Li-Ion and Li-Poly battery-powered information appliances requiring long-term A1A嘉泰姆

battery life.A1A嘉泰姆
