In one embodiment, a self-gated transistor includes a sensing portion that generates a sense signal that is used to drive the self-gated transistor.

Method of forming a self-gated transistor and structure therefor

An inrush current limiter circuit () includes a detection circuit () that produces a control signal (V) from a sense current (I). A power transistor responds to the control signal and has a source () coupled to an input node () to receive a supply voltage (ground) and a drain () for routing a load current (I) to an output node () as a protection signal (V). A sense transistor responds to the control signal and has a source scaled to the source of the power transistor and coupled to the input node to route a portion of the load current to the output node as the sense current.
