This set allows the designer to tailor the startup ramp, fault response, and voltage thresholds to the specific load capacitance and supply characteristics of the target backplane. The controller does not integrate an internal switch — it drives an external N-channel MOSFET. The Rds(on) of that external FET at operating junction temperature, not the 25°C headline, sets the conduction loss and must stay inside the SOA during the inrush event. ## Sourcing posture and lifecycle Active lifecycle status and ROHS3 compliance mean the LT4256-3CGN#PBF is a current-production part.","metaTitle":"LT4256-3CGN#PBF Hot Swap Controller, 10.8-80V, SSOP-16","metaDescription":"Analog Devices LT4256-3CGN#PBF Hot Swap Controller. 10.8V-80V supply, 1.8mA supply current.
