As well as the oddly described thresholds, the (more extensive) AOZ7270 data sheet has many tantalising but unexplained application circuits combining two active diodes with two standard rectifier ...

Both are also available in die form. Further data on the mosfet is sadly not public at the moment, but the diode data sheet is available and shows a 2.1V typical forward drop at Tj = 25°C, increasing ...
