  • TI Thinks Resolved

charge for 5S input voltage is 22-30V, integrated FET.

I use lmr 4020 plus ina 169 for the CC. Plus the SSR. It is cheap and without superfluous logic.

  • Andrew,

    What is lmr 4020 mentioned in your post?

    Thank you,

    I found a solution for me.
    The first variant was with TPS26600PWPR + LMR14020SDDAR + for CC OPA2188
    but, this variant work up to 40V.
    I use the now LMR16020PDDAR + INA169.

    TPS26600PWPR cleaned and supplied the diode.

    Andrew.
