Hi,
I can't understand the function of Vauxh pin. There is not much description in the datasheet. Is it just an auxiliary input? What is the difference between Vauxh and Vcc?
Thanks!

The Block Diagram shows that VAUXH is a voltage monitor input, while VCC is a supply voltage input pin. VAUXH has accuracy specifications in the Electrical Characteristics Table and the PMBus Command Support description.
