        Just to get verify on LTC4054-4.2, programming resistor value. As per datasheet, I have selected 20mA (0.286C) constant charging current. In order to fix 20mA charging current on LTC4054-4.2, R_prog = 1000/(0.020) = 50kOhm Is this correct resistor value to proceed with this IC?

        If the battery is charging and terminating normally, then I don't see a problem. That said, you should look at the charge voltage/current on a scope and ensure that you don't see oscillations.

        … by formula from Datasheet. This meander created from pulsed voltage on our power source.Oscillation frequency is ~ 3.7KHz.Is stable operation LTC4054-4.2 from such a pulsating power source possible? P.S. Our power supply is strictly less than adheres to values MAX electrical characteristic LTC4054-4.2.

        Hello, This could be just fine. You should take a look at the termination of charge. Make sure that the termination is still working correctly and that the battery does not get over-charged with time. The plot seems to show the voltage going up to 1V? I don't …
