Question about UCD90120A GUI setting

Other Parts Discussed in Thread: UCD90120A, UCD90SEQ64EVM-650

Please let me know about GUI setting of UCD90120A below.

①Fusion Digital Power Designer

　・Can UCD90120A variable "Fault to Alert" time on resister setting? 

　・About alert function of voltage monitoring, can alert GPIO collectively one channel?

　　※For example; monitoring 10 voltage rail condition,

　　　　　　　　　if someone has over warn, customer hope that from the same GPIO alert output. 

　・We cant configuration WDI setting, is there condition of configuration Watch Dog time?

②Fusion Digital Power Manufacturing Tool 

　・Is there way of check the address of UCD90SEQ64EVM-650?

　　I forgot address and run script was not complete.

Best regards,

Satoshi

    Hi Satoshi,

    [1] The "Fault to Alert " time cannot be changed by register setting. Once fault occurs, Alert will assert.

    [2] PMBus interface has a Alert pin, and it will response to all power rails' faults. This is what you need I hope?

    [3] For the WDI setting. Go to --Global Configuration--system watchdog.

    Also make sure you have assigned at least one GPI pin.

    [4] We cannot use Manufacturing GUI to check device Address. If you forgot the EVM address, please use Fusion GUI to check it.

    Thanks,

    Luke

    You can also use Logic GPOs to  response the faults you specified.  And the response time can be specified by yourself.

    Let's take your case as an example:

    If  you are monitoring  10 power rails' voltage, and what we want is any fault  of the 10 power rails will trigger the same GPO output.

    The logic would be  Y= V1+V2+V3+.........V10 =  Not{  V1' &&  V2' && V3' ...........&&V10' }

    Go to Hardware configure-->Logic controlled GPO

    Press configure

    I selected to response for Over voltage faults, you can specify your own.

    Also, we can specify the response time here:

    Thanks,

    Luke
