The TPS7H2211 can be used to protect a load from an upstream latchup sensitive regulator. The eFuse will provide overvoltage protection (OVP) and under-voltage protection (by using the EN pin). If the upstream regulator fails, the eFuse will disconnect the load from the regulator. The load could then be powered by a redundant supply (see the Application 1: Cold Sparing section).
In this configuration, the on-resistance of the switch is more important as it is placed after the point of load regulator. Two eFuses can be placed in parallel to further reduce the on-resistance. In the design example shown here, it was determined only one eFuse was needed.
