摘要： A method for controlling the in-rush current to a hot plug device. The method includes providing a series of turn on pulses to the gates of a plurality of turn on FETs on a hot plug device coupled to a direct current power source, wherein each pulse causes the plurality of FETs to pass current from the direct current power source to a subsystem of the hot plug device, and wherein each pulse has a duration that ends before the impedance of the turn on FETs falls below a safe operating region. The method further includes providing a steady turn on signal to the FETs in response to the output voltage from the FETs to a subsystem of the hot plug device exceeding a predetermined voltage threshold.

摘要： A method of controlling the inrush current to a hot plug device. The method includes directing current from an input power rail of the hot plug device to an output power rail of the hot plug device through a high impedance auxiliary current path, wherein an electronic subsystem of the hot plug device is coupled to the output power rail. The method further includes allowing current from the input power rail to pass through a plurality of main turn on FETs to the output power rail in response to the output power rail having a voltage that exceeds a voltage threshold as a result of directing current through the high impedance auxiliary current path.

摘要： A computer planar includes an enable signal line for providing an enable signal to an external power supply, wherein the external power supply will not turn on unless the enable signal is active high. During normal operation, an auxiliary power source maintains an active high enable signal on the enable signal line, which includes a fuse. However, a fault protection circuit coupled to the enable signal line can pull down the enable signal line in response to a fault, such that the fuse is permanently opened. Once the fuse is open, the external power supply cannot be enabled and further damage to the computer planar is prevented.
