DESCRIPTION
The MCP18480 is a Hot Swap controller that allows boards to be safely removed or inserted from an active backplane using -48V. When PCBs are inserted into a live backplane, highpeak or transient currents from the source are generated due to the charging of the bypass capacitors on the supply. The high transient currents can destroy connectors and capacitors. The high inrush current can pull the input voltage BUS down and reset the system. The MCP18480 solves this problem by controlling the slew rate of the backplane voltage to the board so that these transients are eliminated.
