TPS4H160-Q1: Reverse Current Protection: What sets the DGND forward voltage limit at 0.6V max and under what If condition? The diode on the EVM (BAS21-7-F) does not appear to meet this spec worst case.

Part Number:TPS4H160-Q1

Referring to the Reverse Current Protection portion of the TPS4H160 data sheet (p.26) it says: "The reverse current protection diode in the GND network forward voltage should be less than 0.6 V in any circumstances."

Why? And at what forward current should Vf be measured? Depending on If, the diode used on the EVM (BAS21-7-F) does not meet this criteria.

Thank you!
