Patent ID: 7671490

Claim:
A power conditioning module, comprising: a plurality of switched output power rails, wherein each switched output power rail comprises: a first field effect transistor drive configured to receive an input and further configured to be controlled by a controller; a second field effect transistor drive configured to be controlled by the controller; and a circuit connected in parallel with said first field effect transistor drive, wherein said circuit is configured to provide reverse current protection and to supply a voltage output to said second field effect transistor drive when the first field effect transistor drive is inactive, said second field effect transistor drive is connected in series with (i) the first field effect transistor drive and (ii) said circuit, wherein the second field effect transistor drive is configured to deliver an output to a hot swap unit coupled to a load, and wherein the output to the hot swap unit is set to a first voltage when the controller activates the first and second field effect transistor drives, and the output is set to a second voltage that is less than the first voltage when the controller activates the first field effect transistor drive and deactivates the second field effect transistor drive.
