    Hi Patrick,

    TPS25940 can be used here by disabling DevSleep mode. Please let me know if you have any specific power level requirements to suggest.
    Hotswap and eFuse does the same job. Hot swap solution uses external FET + hot-swap controller, where as eFuse is a fully integrated solution. In other words, eFuse can be called as "integrated Hot-swap" device.
