UCD9090A: UCD9090A watchdog timer issue

Part Number: UCD9090A

Hi all,

if we use UCD9090A GPIO14 as a watchdog timer function, so i just want to confirm that if UCD9090A watchdog reset fail, could UCD9090A perform a re-sequence of the power rails if the WDT trips？

Thanks.

    Hi Mason

    The WDT event can not trigger the re-sequencing of the power rails internally. A external circuity is required to loop the WDT signal back to device to do the re-sequence.
