    Hello

    The CHG pin will be a low during the charge.  LED would be connected from Vin to CHG using a resistor. Using the BAT as a power source is an option also.

    If input is used note the max input voltage.  If BAT is used note the additional current draw on battery.

    Also see FAQ that describes the CHG pin.
