一,产品概述(General Description)
          The JTM5453T product is a high integration solution for lithium-ion/polymer battery
protection. JTM5453T contains advanced power MOSFET, high-accuracy voltage detection
circuits and delay circuits. JTM5453T 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.
        JTM5453T 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.
