TCAN4550-Q1: What is the abmax of ISUP?

What is the abmax of ISUP for TCAN4550-Q1?

in the datasheet, it shows USPU mac is 180mA when Dominant with bus fault, but i guess abmax is higher than this, right?

    Hello Jomori-san,

    We do not have abs max specification on input current, and only specify an abs max on output current specs.  The 180mA max current for a Dominant with bus fault condition is the maximum current that would be consumed across all devices and and manufacturing process, voltage, and temperature conditions without an additional load on VCCOUT.  If you will be using VCCOUT to supply external circuits, the you will need to add the VCCOUT current to to the dominant with bus fault max current to get a total supply current.

    Regards,
