MP5014A 10-13.8V, 5A Programmable Current-Limit Switch TSOT23
The MPS MP5014A is a Programmable Current-Limit Switch. It operates from a 10 V to 13.8 V input and is rated for 5 A. It is supplied in a TSOT23 package.
The MP5014A is a protection device designed to protect circuitry on the output (source) from transients on the input (VCC).

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.
