    MP5991 4-16V, 50A Hot-Swap Intelli-Fuse Solution LGA-32

    The MPS MP5991 is a Hot-Swap Intelli-Fuse Solution. It operates from a 4 V to 16 V input and is rated for 50 A. It is supplied in a LGA-32 package.

    The MP5991 is an integrated, monolithic controller and switch with a power MOSFET and other circuitry that allows it to work in standalone operation or to be controlled via a hot-swap controller.

    Design Notes

    • The current-limit threshold must stay inside the SOA of the pass device at the applied voltage, including startup inrush.
    • Hot-swap inrush control is set by the slew rate on the gate or the dV/dt capacitor — too fast trips the upstream supply.
    • Reverse-current blocking behaviour differs between ideal-diode and load-switch topologies; pick the one that matches the fault you are protecting against.
    • Route the fault flag to a pin the firmware actually polls; a latch-off protection with no report looks like a dead board in the field.
