Hi dear supporting team,

for the Vin mentioned in below curve, which point voltage does it mean? (A1~3, B1~3) , And how about Iin, is it Ipass?  TKS A LOT!

    Hello Vera,

    The graph for the On-Resistance above was created using the same methods which they used to create the table with Ron spec. In this case they measure the voltage drop across Ax to Bx, where x corresponds to 1, 2, or 3. Please see the snippet I have attached below from our datasheets:

    The answer to the second question about Iin is yes, Iin in this case is the same as Ipass as well as Io from the above table.

    Thanks,

    Louie
