    MCP18480
    -48V Hot Swap Controller
    Features Description Allows safe board removal and insertion from a
    live backplane Accurate (<1.5%) internal voltage reference for
    fault detection and precision timing Programmable foldback current limiting Programmable circuit breaker current limiting Auto restart option for all faults Adjustable Undervoltage lockout thresholds Adjustable Overvoltage protection threshold Adjustable Power Good delay Configurable Power Good output polarity Low-side drive of an external N-channel FET The MCP18480 is a Hot Swap controller that allows
    boards to be safely removed or inserted from an active
    backplane using -48V. CMOS Technology High-Voltage Operation Temperature range: Industrial (I): -40В°C to +85В°C Packaging 20-lead SSOP Package Type

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. This allows boards to
    be removed and inserted without causing damage to
    connector pins and input bulk capacitors, in addition to
    preventing false resets to the other boards on the
    backplane.
    The MCP18480 can be used in applications in several
    areas including: Telecom Line Cards
    Network Switches
    Network Routers and Servers ...
