The LTC4217, which combines a Hot Swap controller, MOSFET and sense resistor in a 5mm 3mm DFN package for accurate current limit and load current monitoring in tight spaces, is described.
Hot Swap controller
In general, a Hot Swap controller provides two important functions to boards that can be plugged and unplugged from a live backplane:
• It limits the potentially destructive inrush current when a board is plugged in.
• It acts as a circuit breaker, with the maximum current and maximum time at that current ...
