Part Number: UCD90124A
Other Parts Discussed in Thread: UCD90120A

Hello team,

My customer is evaluating UCD90124A with Fusion software for power control of CT scanner system, then they have a question.

Could you help confirm that UCD90124A doesn’t support rails fault response based on GPI, except the first three GPI pins?
The customer got the menu as below, which is different from the figure in the user manual of Fusion Digital Power Designer GUI 7.0 for the UCD90xxx Sequencer. (SLVUB51)

Your help is appreciated.

    Hi

    Yes, for the UCD90124A, the only way to use GPI to turn on/off rail is the PIN SELECTED RAIL STATE.

    GPI fault shutdown is not available on UCD90120A 

    the snapshot is from different device as example.

    Regards
