Other Parts Discussed in Thread: LM5066, TPS4812-Q1
We would like to use the LM5066 in a ~40A bidirectional application, where current is measured and protected in both direction, such as in a battery source with reverse current charging. Do you see any issues in using two back-to-back LM5066H in the manner shown in the image? They would share a single Rsns but each have a FET.
Both LM5066H would be fed by "Vrail" which is an always on supply. Can VIN be supplied by another lower voltage?

On a related topic, is the TPS4812-Q1 capable of overcurrent protection in both current directions?
