48 V Hotswap for rack / blade servers

Much of the infrastructure that runs our current 24/7 online world is made up of 12 / 48 V rack-based server systems that are permanently live. So, the boards and components that drive these systems must be able to be ‘hot-swapped’ to allow for upgrades and maintenance without ever needing to power down the equipment.

Design considerations

  • When a board is plugged into a live system, it is important the in-rush current is carefully controlled to protect the components on the board and ensure other parts of the system do not experience any power disruption.
  • MOSFETs with a strong linear mode performance and enhanced safe operating area (SOA) are required to manage this current effectively and reliably
  • Once the replacement board is safely installed, the MOSFET is turned fully ON. In this mode of operation, a low RDS(on) value is of primary importance, helping to keep temperatures down and system efficiency at a maximum
