    Hello,

    What is your battery voltage when this is happening? The input voltage must be above the battery voltage because this is a buck charger.

    Also, you will need to adjust your OVPSET divider. With a 5 V input, OVPSET is 0.45 V which is below 0.5 V and indicates undervoltage.

    Thanks,

    Mike Emanuel
