9.2.1 Redundancy

In applications where primary and secondary (redundant) power rails are present, the TPS7H2201 is ideal to implement redundancy because of its reverse current blocking capability. In this case, since the eFuse is placed at the input of the point of load regulator, the on-resistance of the switch is not as critical.
