        (充電芯片)HP4060(TDFN1*1 帶EN)

        The HP4060 series of devices are highly integrated Li-Ion
        and Li-Pol linear chargers targeted at small capacity
        battery for portable applications. It is a complete
        constant-current/ constant voltage linear charger. No
        external sense resistor is needed, and no blocking diode
        is required due to the internal MOSFET architecture. It
        can deliver up to 300mA of charge current (using a good
        thermal PCB layout) with a final float voltage accuracy of
        ±1%. The charge voltage is fixed at 4.2V, 4.35V or 4.4V,
        and the charge current can be programmed externally
        with a single resistor. The charger function has high
        accuracy current and voltage regulation loops and
        charge termination.
        The HP4060 automatically terminates the charge cycle
        when the charge current drops to 1/10 the programmed
        value after the final float voltage is reached.
        When the input supply (wall adapter or USB supply) is
        removed, the HP4060 will shut off, only 40nA leakage
        current coming from battery at sleep mode when
        ambient temperature is 85, so it can save energy and
        improve standby time.
        The HP4060 is available in a small package with
        TDFN1X1-6L. Standard product is Pb-Free and Halogen
