LTC4259ACGW - Brand New Analog Devices / Linear Technology Power Over Ethernet Controllers
-
Description
The LTC4259ACGW is an electronic component model classified as a Power Over Ethernet Controller. It is equipped with the LTC®4252 negative voltage Hot SwapTM controller, which provides a safe method for inserting and removing a board from a live backplane. The controller features three stages of current limiting to ensure controlled output current, including a timed circuit breaker, active current limiting, and a fast feedforward path that limits peak current under worst-case catastrophic fault conditions.
