    Thread Summary
    
                The user inquired about the overvoltage cut-off functionality of the LTC4364, which was not working as expected. The support engineer clarified that the overvoltage cut-off only activates during initial power-up if the OV pin voltage exceeds 1.25V before the 100μs power-on-reset. For continuous overvoltage protection, the FB pin must be connected and configured, as shown in the datasheet.

    Hi Team,
    

    We have designed LTC4364 for circuit for under and over voltage protection, this design the under voltage cut off functionality was working properly, but the Over voltage cut off  functionality Not.
    

    We have set the over voltage cut off at 40V, anyone please answer why this feature not working.
    

    Our Schematics attached below please review the same and share the feedback.
    

     
    

    Regards,
