Part Number: UCD90120A

Hi,

I need to access the status register to read the Vout UV Warning bit and can't figure out what commands to access this register.

Thanks,

Jordan

Do you mean STATUS_VOUT(0x7A) command to tell the status of a given rail? This is standard PMBus command.

You can refer section 17.3

It is a paged command. so you have to issue PAGE_COMMAND(0x0) to select the target rail first followed by STATUS_VOUT command.
