UCD9090A：Can the rails be used at the same timing?

Part Number: UCD9090A

Hi Teams,

My customer is trying to implement a power sequence for an FPGA using a power sequencer.

Nine power supplies are controlled for 13 power supplies. When turned off, the procedure is the reverse of that for rising.

Should I use UCD9090A, which is for power supply sequencer for 10-rail control?

Customers want to use small packages as much as possible.

Best Regards,

Kenji

    Hi

    What do you mean" nine power supplies controlled for 13 power supplies? How many rail to monitor, how many rail to sequence?

    UCD9090A can monitor up to 10 rail, but it can sequence more than 13 rails.

    is this information sufficient? if not, please provide more details of your requirements.

    Regards

    Yihe
