LTC4274AIUHF-2#PBF - Brand New Analog Devices / Linear Technology Power Over Ethernet Controllers
-
Description
The LTC4274AIUHF-2#PBF is a 2-channel Hot SwapTM controller that allows a board to be safely inserted and removed from a live backplane. It uses two independent high side gate drivers to control two external N-channel pass transistors, enabling the ramping up of output voltages with current foldback to limit the inrush current during the start-up period. No external compensation capacitors are required at the GATE pins. The two channels can be configured to ramp up and down separately or simultaneously for supply voltages ranging from 2.7V to 13.5V and 1V to 13.5V for channels 1 and 2 respectively.
