Hi,I want use a mosfet driver (UCC27323D) with a 4V supply. In the datasheet it's write "4.5-V to 15-V Supply Voltage" but in the web site of ti it's writed: "Vcc min 4V"...What is the Vcc min?Thanks,
When in doubt... follow what the datasheet says. Whatever was in the site is irrelevant if opposes what the datasheet says
Remember, that the thresholdvoltage on your MOSFETs must be below the 4V (supply voltage of UCC27323).
I recommend using e.g. 12V supply.
