LTC4216 - Ultralow Voltage Hot Swap Controller

General Description

The LTC®4216 is a positive low voltage Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane.

It controls load voltages ranging from 0V to 6V and isolates a severe fault with instantaneous analog current limiting.
