Mission-critical servers and communication equipment must continue operating even as circuit boards and cards are plugged
in or pulled out for maintenance or capacity adjustment. Hot swap controllers enable board insertion and removal from live
systems by soft-starting the supply, avoiding connector sparks, backplane supply glitches, and card resets. In addition to inrush
current control, hot swap controllers provide fault isolation with a circuit breaker, undervoltage (UV) and overvoltage (OV) lockout,
and digital telemetry of board electrical parameters. Analog Devices delivers leading-edge hot swap innovations and tough,
dependable protection for high availability systems.
