Abstract: A device includes first and second device terminals, a fuse, a first circuit, a first transistor, and a control circuit. The fuse terminal couples to the first device terminal. The first circuit couples to the second fuse terminal. The second fuse terminal has a first voltage. The first transistor has a first control input and first and second current terminals. The first current terminal couples to the second fuse terminal, and the second current terminal couples to the second device terminal. The control circuit: turns “on” the first transistor into a saturation region if the first voltage exceeds a threshold and a current through the fuse exceeds a trip threshold current of the fuse; and turns “on” the first transistor into a linear region if the first voltage exceeds a threshold and a current through the fuse is below the trip threshold current of the fuse.

Abstract: A circuit includes a supply circuit having an input and an output. The supply circuit includes: a capacitor having a first terminal and a second terminal, the first terminal of the capacitor coupled to the output of the supply circuit; a switch having a first terminal, a second terminal, and a control terminal, the first terminal of the switch coupled to the input of the supply circuit, the second terminal of the switch coupled to the output of the supply circuit; and a controller coupled to the control terminal of the switch. The controller is configured to: turn on the switch responsive to a first supply voltage level at the input of the supply circuit; and turn off the switch responsive to a second supply voltage level at the input of the supply circuit.
