в–  The LTCВ®4085-1 is a USB power manager and Li-Ion
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 Battery, USB and 5V Wall Adapter
215mО© Internal Ideal Diode Plus Optional External
Ideal Diode Controller Provide Low Loss PowerPathTM
When Wall Adapter/USB Input Not Present
Load Dependent Charging Guarantees Accurate USB
