Forum Post: problem about UCD9222's VID

Hi all,

In C6678 EVM schematics, I found that one channel of the UCD9222 connected C6678's VID pins. This channel will control the UCD7242 to output the scaled voltage.

The other channel of UCD9222 must control the UCD7242 to output fixed voltage. Does this mean that the VID pins of this channel are not necessary to connect anythings? But in the C6678 EVM schematics, this channel's VID pins connect to FPGA, I want to know what the FPGA has done about the UCD9222?

Thanks for any replies!
