UCD9081* PROGRAMMING OUTPUT

Other Parts Discussed in Thread: UCD9081EVM, UCD9081

USING UCD9081EVM, we cant change/control  output voltages .Where can be the problem?

  • UCD9081 is a sequencer. It cannot change rail voltage, but only enable/disable rails according user-defined sequence and report fault.

    With default configuration, there is no sequence or dependency and all rails should be turned on automatically. If some rails cannot be turned on, check Sequencing Conditions. Also, check jumper locations to see whether EN signals are disconnected from on-board power supplies.

    Thanks,
