AMC1304M25: TIEVM-HV-1PH-DCAC excel file content does not understand

Part Number: AMC1304M25

Hi team,

One of our customers does not understand the content in the Excel file below, could you please help explain this?


In Vbus, the Reffective is a parallel between Rh and Rdiff, which is not understood here.

And why is Rdiff 12.5k? I see in the AMC1304X25 datasheet that the RID is 25kΩ.Does the RID in the datasheet refer to Rdiff? If not, why is Rdiff 12.5KΩ, could you please help explain?

Best Regards,

Amy Luo
