Not a latching circuit. On over current the MOSFET is supposed to turn off, which brings current back into normal limits, which brings back the overcurrent condition ... a saw tooth generator. It may limit the current to a specific level, but it does not remove power until a button is pushed....................

If you are referring to the circuit I posted it does indeed latch until the power or load is removed.
Here's an explanation.

Interesting.
