UCD90120A: watchdog timeout

Michael T Schneider

Part Number: UCD90120A

Hello Team, 

We are using a UCD90120A Power Sequencer in a design that was found to have an issue in qualification.

We are using both the older version and the newer version of the tool.

We are trying to use the watchdog feature.

It does not appear that we have the capability to do anything with the triggered watchdog but toggle an IO.

We would really like to hook up the watchdog timeout to a resequence event?

(Without having to add a wire to the design)

 

Please advise,

    Hello

    Without knowing the whole picture, my answer only focus on the WATCHDOG function.

    The watchdog event does not support resequence unless a hardware support(wire) is present.

    are there any other signals available between the host and UCD in the design? if you can share, I can take a look.

    Regards

    Yihe
