    MPQ5074-AEC1 1.2-5.5V, 3A Low-RDS(ON) Load Switch QFN-13

    The MPS MPQ5074-AEC1 is a Low-RDS(ON) Load Switch. It operates from a 1.2 V to 5.5 V input and is rated for 3 A. It is supplied in a QFN-13 package. The part is AEC-Q100 qualified.

    The MPQ5074 provides up to 3A of load current (ILOAD) across a 1.2V to 5.5V input voltage (VIN) range.

    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.
