  • Patent number: 11594870
    Abstract: A hot-swap circuit for providing soft start and overcurrent protection to an electronic circuit may include a controller and a timer. The controller may be configured to sense an electrical current associated with the hot-swap circuit, based on the electrical current sensed, perform current limiting of the electrical current to minimize inrush current to the electronic circuit, and disable the electrical current from flowing to the electronic circuit in response to the electrical current exceeding an overcurrent threshold for longer than a duration of a fault timer. The timer circuit may be configured to, for a period of time after enabling of the hot-swap circuit, cause the duration of the fault timer to be a first duration, and after the period of time, cause the duration of the fault timer to be a second duration significantly shorter than the first duration.
