    Is it possible to test that the MCU output which modulates the FETs ‘gates is working ? (I assume this is how it should work?

    Maybe the problem is there.

    I was surprised the C4 voltage was higher that the cell – maybe because of differing track resistances?

    Does the fact I can control the charging current with the VR confirm that part of the circuit is working? ie the neg feedback section.

    I am using LT1677s

    Thanks
