Linear Technology offer a range of Hot Swap controllers providing circuit protection by limiting inrush current as well as fault isolation. They allow electronic circuit boards and cards to be inserted into live system backplanes. Hot Swap controller will sense, control and operate continuously as the boards are hot plugged in or pulled out. They can present board power monitoring via digital measurements of the current and voltage levels by integrated ADCs, accessible through I2C/SMBus interfaces. Linear Technology’s Hot Swap controllers utilise N-channel MOSFETs to control power flow, which allows a wide range of load currents and operating voltages.

These devices are often used in applications such as:
Server rack mount systems
Distributed power systems
Medical Systems, Telecom systems
Set Top Boxes
High side switch/circuit breakers
Switchers / Routers
