Protection Circuitry for Hot Swap    

Protection of circuitry during a hot swap event.

Overview

Hot-swap enabled technology, refers to the ability to plug in and plug out electronic based products in and out of a system while the system is powered on. Hot-swap technology is in widespread use in telecommunications, power management and other equipment. Hot swap protection circuitry includes overcorrect decoupling power from a load, ground-fault conditions and noise reduction in the power that is delivered to the load.
