UC1708-SP: Unused Channels?

Part Number: UC1708-SP

Hi Team,

I have a different question on the UC1708-SP. If I’m only using one of the two outputs, what is your recommendation for the INPUT and OUTPUT pins of the unused channel for lowest power consumption?

Thanks!

Connor

    Hey Connor,

    The suggestion is to keep the outputs floating and tie the inputs to a stable voltage.


    If you have the outputs tied to something you will have the device forcing extra drive and perhaps shorting
    (You could also have a small capacitance)

    The inputs are safest tied to something that will keep the output low.
    This will make it so noise wont have the output switch.

    Thanks,
    Daniel
