Hot Swap

Protection and Convenience


The ability to hot swap memory, drives, or other peripherals is a key functionality of server, computing, and telecom hardware. ON Semiconductor’s load switch and eFuse portfolios provide an easy, compact, and efficient solution with the hot swap controller and MOSFET integrated into one device.

ON Semiconductor carries eFuses for 12 V, 5 V, and 3.3 V power domains, with 48 V compatible devices in development. We use the latest MOSFET technology to provide efficient, reliable, and compact hot swap capability with a variety of protection features such as:

  • Configurable overcurrent protection
  • Overvoltage and undervoltage protection
  • Adjustable output slew rate to control inrush currents
  • Thermal shutdown
  • Fault reporting
  • Auto-reset
  • Easy paralleling
