  • Publication number: 20200044439
    Abstract: A current limiting circuit for controlling current from a power supply to a load having a capacitance includes an inductor, a transistor coupled in a current path with the inductor, and a control circuit. The transistor includes a control terminal. The control circuit is coupled to sense a voltage across the inductor and coupled to the control terminal of the transistor. The control circuit is configured to turn off the transistor when the voltage across the inductor is greater than a threshold to restrict current from a power supply, and turn on the transistor when a defined parameter is met to allow current from the power supply to charge the load capacitance. Other example current limiting circuits are also disclosed.
