LTC4282 is a hot swap controller allows a board to be safely inserted and removed from a live backplane. Using one or more external N-channel pass transistors, board supply voltage and inrush current are ramped up at an adjustable rate. An I²C interface and onboard ADC allows for monitoring of board current, voltage, power, energy and fault status. Dual 12V gate drive allows high power applications to either share safe operating area across parallel MOSFETs or support a 2-stage start-up that first charges the load capacitance followed by enabling a low on-resistance path to the load. It is well suited to high power applications because the precise monitoring capability and accurate current limiting reduce the extremes in which both loads and power supplies must safely operate. It is used in applications such as enterprise servers and data storage systems, network routers and switches, base stations, platform management etc.
