The V5DRV is basically a power out pin
That would connect to a power net somewhere. I'll guess to the LED string
or power LED
You can either connect it with a line or put some form of power flag on
it, with the LEDs connected to the same net but be careful as you have
multiple copies of the driver on the cct that you make each one a
different net or erc will really complain.

I have a schematic that is throwing a spurious warning. The schematic
is hierarchical, with multiple instances of a LED driver IC with
associated LEDs. To allow each of the LED drivers to be identified on
the I2C bus, I have exported the three address-setting pins and the 5V
rail (each driver is on its own filtered 5V supply). Each
address-setting pin can be connected to ground, 5V, or left floating,
all three having a significance to setting the I2C address.
The eeschema ERC has no problems with the address lines being marked
with a no-connection flag, but it chokes on the 5V output being so
marked, giving a warning, 'A pin with a "no connection" flag is
connected'. If I remove the no-connection flag from the 5V output, I
then get an error, 'Pin not connected'.
I could just ignore the warning, but since I don't understand what is
the problem, I thought I would first ask if anyone knows.
Hopefully the screen-shot I've attached is visible to you and clarifies
what I'm describing.
Regards,
Robert.
