Hot Swap Controllers:

473 Products Found

Newark offers a comprehensive range of hot swap controllers from industry-leading manufacturers, featuring solutions for both low and high voltage applications, with options for I²C programmability and advanced diagnostic capabilities.

Hot-swap controllers are integrated circuits that manage how electronic cards and boards are inserted into the live system backplane. The controller's purpose is to control the inrush current and isolate faults. These controllers are crucial components in power management systems, protecting both the system and its components.

As the hot swap board is plugged into the system, the controller detects the power and gently ramps up the board’s capacitors to avoid sparking at the connectors, system resets, backplane supply glitches, and other associated malfunctions that the insertion may cause.

Applications span data centers and telecommunications equipment to industrial automation systems. Hot swapping is applicable to servers, communication equipment, medical equipment, and other equipment used for critical applications where shutting down a system cannot be allowed or would cause undesired effects. The swapping is usually done when replacing faulty units, upgrading, or repairing equipment.

Key benefits include enhanced system reliability and uptime, reduced maintenance costs, protection against short circuits and overload conditions, safe live system servicing, and extended equipment lifespan.
