一,产品概述(General Description)
GENERAL DESCRIPTION
    The JTM5456 product is a high integration solution for lithium-ion/polymer battery protection.
    JTM5456 contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits.
    JTM5456 is put into an ultra-small SOT23-5 package and only one external component makes it an ideal solution in limited space of battery pack.
   JTM5456 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.
