  • Fuse having parallel transorb device with switch
    Patent number: 11251607
    Abstract: An electronic fuse (e-fuse) for controlling input current of a load includes a transistor switch and a transorb device that is coupled in parallel to the transistor switch between a source and a drain of the transistor switch. A circuit comprising the transistor switch and the transorb device in parallel comprises a first end and a second end. The first end of the circuit is coupled to a power bus. The second end of the circuit is coupled to a first node of the load. The e-fuse includes an RC circuit comprising a resistor coupled in series with a first capacitor. The RC circuit is coupled between the power bus at the first end of the circuit and a return. The return is coupled to a second node of the load. The e-fuse includes a second capacitor that is coupled between the return and the second end of the circuit.
