摘要：An inrush current controller for a device has a connector for hot-plugging the device into a source of energization. An impedance has a current input coupled to a first contact of the connector and a current output coupled to the device. The impedance has an impedance control input. An impedance control circuit has a logic input coupling to a second contact of the connector. The impedance control circuit has an impedance control output connected to the impedance control input. The impedance control output forces the impedance OFF during a first time interval after hot-plugging. The logic input triggers a limited inrush at the current input after the first time interval.
