Dear all.

Does the 'VDD Clamp Over-Current' and 'Thermal shutdown' fault auto reboot?

    Hi Pan,
    The protection mechanism for "VDD Clamp OVer-current" is fault auto reboot which is describted as "auto restart" on page 24 of UCC28911 datasheet.
    For "thermal shutodwn", it is a little different. if the temperature is still above 100℃ after the thermal fault, the VDD will go down and up like "auto restart" but no pulse produced. the IC will produce pulse until the temperature go down below 100℃
