Presented systems and methods can facilitate efficient switching and protection in electronic systems. A system can comprise: an input operable to receive a signal; an adjustable component configurable to operate in a first mode which includes a low resistance and the component configurable to operate in a second mode which includes a current limiting operation in which the second mode enables continued operation in conditions that are unsafe for operation in the first mode; and an output operable to forward a signal. The adjustable component can be configurable to turn off if unsafe to operate in either the first mode or second mode. The first mode can include a relatively large component configuration with a relatively low drain to source on resistance. Utilizing a small component configuration in the second mode can include a relatively increased gate to source voltage compared to a large component configuration in the second mode.

Current limiting systems and methods

In one embodiment, a circuit includes a resistance including first and second terminals. The first terminal of the resistance is coupled to ground. The circuit also includes a first switching element including first, second, and third terminals. The first terminal of the first switching element is coupled to an output of an integrated circuit and the second terminal of the first switching element is coupled to a voltage supply of the integrated circuit. Additionally, the circuit includes a second switching element including first, second, and third terminals. The first terminal of the second switching element is coupled to an enable input of the integrated circuit. Furthermore, the second terminal of the second switching element is coupled to the third terminal of the first switching element and to the second terminal of the resistance. Moreover, the third terminal of the second switching element is coupled to the ground.
