Do any Load Switches work with a negative voltage input?

Roger Perry

I have a -12V power circuit, and I am looking to see if there is a load switch that can put in the output line and control with a 3.3V enable signal.

I had done a search but did not see any available?

Thanks,

Roger

    Hi Roger, 

    Thanks for reaching out on E2E!

    Unfortunately, from a load switch perspective, we don't have any devices currently capable of switching negative voltage rails. Some of the internal circuitry could be damaged by biasing them incorrectly. 

    Thanks,
