ABSTRACT:
A two-step approach to power up a host bus adapter (HBA) or other adapter card during a live insertion is disclosed. A low power linear regulator provides early power while the system is in its reset state, then a FET is gradually turned on using a Hot Swap Controller to provide operational power to the HBA, at which time the linear regulator is disabled. The linear regulator provides early power to pre-charge the CompactPCI signal interface on the HBA and place the HBA CompactPCI drivers in tri-state while the HBA is held in reset.
