        The XB4302 series product is a high
        integration solution for lithium-
        ion/polymer battery protection. XB4302
        contains advanced power MOSFET,
        high-accuracy voltage detection circuits
        and delay circuits. XB4302 is put into an
        ultra-small TSOT23-4 package and only
        one external component makes it an
        ideal solution in limited space of battery
        XB4302 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.
