The short circuit protection design of power MOSFET, as the name suggests, is the design of fast protection of MOSFET when the MOSFET current is rapidly increased due to short circuit in the circuit.

In theory, this design can prevent MOSFET damage in the case of short circuit. The short circuit protection design is very important for the reliability of the system, which not only prevents the MOSFETs from being damaged due to overcurrent, but also helps to protect other critical devices in the circuit, such as magnetic components, resistance and capacitance devices. Of course, the short-circuit protection design should take into account both the rapidity of the action and the protection of some transient overcurrent in the work, so the relevant parameters need to be designed according to the actual application.
