    DESCRIPTION FEATURES
    в–  в–  в–  в–  в–  в–  в–  в–  в–  The LTCВ®4085-3/LTC4085-4 is a USB power manager
    and Li-Ion/Polymer battery charger designed for portable
    battery-powered applications. The part controls the total
    current used by the USB peripheral for operation and
    battery charging. The total input current can be limited to
    20% or 100% of a programmed value up to 1.5A (typically
    100mA or 500mA). Battery charge current is automatically reduced such that the sum of the load current and
    charge current does not exceed the programmed input
    current limit. Seamless Transition Between Input Power Sources:
    Li-Ion/Polymer Battery, USB and 5V Wall Adapter
