Hot Swap Controllers VIN VOUT TO LOAD 10V/DIV CURRENT NFET CONTACT VIN BOUNCE SENSE DRIVE INRUSH 0.2A/DIV IIN CONNECTOR 1 CONNECTOR 2 OUTPUT CURRENT UV HOT SWAP MONITOR CONTROLLER OV VOUT SOFT-START POWERGOOD DC/DC 10V/DIV FAULT ENABLE TIMER POWERGOOD GND 20ms/DIV BACKPLANE PLUG-IN BOARD Inrush Control Circuit Breaker Telemetry UV/OV Protection Mission-critical servers and communication equipment must continue operating even as circuit boards and cards are plugged in or pulled out for maintenance and 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.
