Current-limited switch with fast transient response

A current-limited switch comprising:

• a power MOSFET;
• a pilot circuit connected in parallel with the power MOSFET, a first pilot MOSFET and a second pilot MOSFET being connected in the pilot circuit;
• a reference circuit comprising a current source and current mirror circuitry, the current mirror circuitry comprising first and second parallel circuits, each parallel circuit comprising a first current mirror MOSFET connected in parallel with a second MOSFET, the first and second parallel circuits being connected in series;
• a difference amplifier having a first input terminal coupled to a point in the pilot circuit and a second terminal coupled to a point in the reference circuit, and having an output terminal coupled to a gate of the power MOSFET;
• and
• a current mirror compensation circuit comprising:
• a first bypass switch for forming a short around the first parallel circuit when a voltage at a terminal of the power MOSFET reaches a first level;
• a second bypass switch for forming a short around the second parallel circuit when the voltage at the terminal of the power MOSFET reaches a second level;
• and
• a voltage-divider circuit, a first node of the voltage divider circuit being coupled to the first bypass switch, a second node of the voltage-divider circuit being coupled to the second bypass switch, wherein the voltage-divider circuit comprises a plurality of voltage-divider MOSFETs connected in series, the second node being located at a point between two of the voltage-divider MOSFETs.
