When using one (or two) of the UCD92xx Digital Power Controllers (e.g. the UCD9246) for the power supply on a PCIexpress card
is it then possible to connect the PMBus of those controllers to the SMBus-Interface which is available on the PCIexpress slot?
This would make it possible to independently monitor the health of the cards power supply with the help of some software (which of course needs to be written).
Has anyone done something like that yet?
Maybe there's even a reference design (for the hardware)?
