Abstract
Hot-plugging and power management capabilities are simultaneously provided for a connector. Circuitry is provided to control a power management terminal so that it is powered up gradually and only after a device has been connected to the connector. The power management terminal is powered down when the device is disconnected from the connector under control of the circuitry. The power management voltage domain is isolated from the voltage domain of the system having the connector by further circuitry which also provides connection status lines.
