UCD9090: How to read the 11th MON pin

Part Number: UCD9090

The part has 11 MON pins, but when I run READ_VOUT, it only works on the first 10.  How can I read the 11th voltage?

    Hello

    UCD9090A is a 10 rail sequencer although it has 11 MON inputs. the 11th MON can not be a independent rail, it need be configured as a either current or temperature monitor along with the other 10 rails.

    you can configure the 11th mon as current but with a 1:1 ration so that the return of READ_IOUT is the same as READ_VOUT. 

    Regards
