TIDA-00893: TCAN1042 supply current

Part Number: TIDA-00893
Other Parts Discussed in Thread: ISOW7841, TCAN1042-Q1, SN65HVD256


Our customer trying isolated can circuit based on TIDA-00893.

We can see that ISOW7841 can supply 130mA max to load in this.

However, TCAN1042 requires 180mA supply current when " Normal mode(dominant – with bus fault)" ,  in the datasheet.

Does this ref design not support bus fault condition ?

If we want to support this too, we have to change power circuit design ?
